Bratwerst Posted February 20, 2004 Share Posted February 20, 2004 Got the head off - and didn't expect THIS: Methinks Mescrewed! Any suggestions - is there any way Im just being nuerotic, or is it that bad.... always looking for a bright side.....

the_bard Posted February 20, 2004 Share Posted February 20, 2004 Granted, I'm a fairly big newbie on the internal workings of engines... but are you referring to the green/yellow corrosion on the stud in the foreground? Sure doesn't look good to me, that's why I'm asking . Quote Link to comment Share on other sites More sharing options...
North Ursalia Posted February 20, 2004 Share Posted February 20, 2004 A little JB Weld and that will be right as rain ! Quote Link to comment Share on other sites More sharing options...
Bratwerst Posted February 20, 2004 Author Share Posted February 20, 2004 I'm referring to the fat chunk of block missing between the two cylinders. Corrosion doesn't bother me that much in comparison N.

subarubrat Posted February 20, 2004 Share Posted February 20, 2004 Just JB weld it, use the old head gaskets and knowing the EA81 you might just get another 100k. Or it might frag, but screw it, find out right? Quote Link to comment Share on other sites More sharing options...
rallyruss Posted February 20, 2004 Share Posted February 20, 2004 no dont jb weld it. if you dont give a crap and just want to make a experiment out of it go ahead. I would not try anythig like that on a motor I would build. the correct answer is just like you assumed. yer skrewd. get another short block.

Skip Posted February 20, 2004 Share Posted February 20, 2004 Sure looks toast to me. How long did you drive it with this problem? Looks like the combustion was passing through this cut out. Head gasket went then the hot gases passing through the opening melted the block and the liners? Odd very odd. Wheres Qman? I would like to hear what he says.

subarubrat Posted February 20, 2004 Share Posted February 20, 2004 Of course get a new short block, I am just suggesting it for sh*ts and giggles. It is comedy gold when something like that works. Quote Link to comment Share on other sites More sharing options...
Bratwerst Posted February 20, 2004 Author Share Posted February 20, 2004 Actually I didn't drive the car with this problem at all - only into my garage. I'm sure you old-timers remember Chewy/Matt - I bought it from him, and he said it always acted wierd since he got it from someone down in Oregon (if any of you remember, this is the car that had the 14" australian wheels on it... ) Thats a reasonable guess Skip - at least it sounds like it makes sense. - Erik Hosa - Tacoma, WA - Quote Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted February 20, 2004 Share Posted February 20, 2004 What rig did this come from? That is definatly a sign of you being screwed. -Brian Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted February 20, 2004 Share Posted February 20, 2004 JB is pretty strong - And that looks to be about your only option short of having someone who can weld aluminium put some metal on there, and having it milled flat.... that, or use this block as your new jack-stand..... I think personally I might actually try JB weld - what's the worst that could happen? Once it's fully cured it should withstand the heat - the pressure I don't know about. Might blow the gasket again. I would certainly use an old gasket if I tried this - would be a pitty to waste a new one on such an experiment.

Bratwerst Posted February 20, 2004 Author Share Posted February 20, 2004 BTW - I'm in no way badmouthing Matt - he didn't screw me over in any way to his knowlege (there was no oil in the water, water in the oil - so he assumed the head was fine... which it is) Brian: the 81-stocker wagon GL (my lifted is the 82) - Erik Hosa - Tacoma, WA - Quote Link to comment Share on other sites More sharing options...
Ratty2Austin Posted February 20, 2004 Share Posted February 20, 2004 the only realistic option here is to get a new shortblock... (hey, they are only about 60 bucks from PAP!) good luck on this one... if you need help fixing this car or getting a shortblock, give me a PM or email or somethin...

rallyruss Posted February 20, 2004 Share Posted February 20, 2004 subaru brat- I could tell that was a joke but I think he was looking for a real answer here. GD - mmmm nope that would not be weldable due to the fact that the liner and the block are both blown thru and so close to one another. and no JB cannot take the heat and pressures of the combustion chamber. used gasket? thats like using used TP to wipe your a$$. single use only. I know some times its fun to try some backwoods enginering but let him get the proper information first. Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted February 20, 2004 Share Posted February 20, 2004 I think it could be welded - no need to weld the liner up - just weld enough aluminium back onto the block to file it down flat and be able to seal. And if you cinch a used gasket down tight enough it will work fine. I've used many old head gaskets without incident. I've also had them blow - it just depends on what shape it's in. Same goes for any gasket - exhaust gaskets are a prime example - they need replacing if they are bad..... nothing bad can come from a used gasket that works - it's only bad if it doesn't work...... I'm just saying that *I* would TRY it. Not that it will work, or that it's something that everyone should consider. These engines are tough, and very rarely do my "backwoods" engineering attempts actually fail. I'm very often pleasently surprised in fact.

Qman Posted February 20, 2004 Share Posted February 20, 2004 Bummer, is this the motor out of the wagon from Matt? I heard it run after we thought the gasket let go. I can say that I haven't seen a Subaru engine do this. The sleeve is definitely gonna be cracked by the look of the seperation at the top. For the long term I would have to say trash it. 1800's are all over the place and much cheaper than any attempted repair would be. I have one that should have a good short block. I should have it out soon. How much you looking to spend? You can get a shortblock cheap enough but then the expense of putting it back together. Is this for a driver or are you gonna sell it once it's running? A used motor from PaP may be the right move at this time. Email me and we'll work some sort of magic for this one.

the_bard Posted February 20, 2004 Share Posted February 20, 2004 Should've spent longer looking at the pic, and more thinking. That's not the head you've got a pic of, it's the block (hence the comment about the heads being alright). Thought that chunk looked smooth enough, it should be there (hence thinking the heads were alright, when I was looking at the block, not the heads, hence the heads are alright, but not the block). Oh, I give up trying to save face . P.S.: Now that I look at it, it doesn't look all that smooth. Ah... oh, well. Quote Link to comment Share on other sites More sharing options...
North Ursalia Posted February 20, 2004 Share Posted February 20, 2004 Am I serious about the JB Weld? Absolutely . Fully cured, the stuff is amazing. My present motor in the 2000 RS had an oil seepage at a casting mark, which got the owner a new block and me a nearly new block (1400 miles). JB Weld fixed it like a charm. The guy who did the repair has gone about 35k miles on his stock car motor fixed with JB Weld. It'll cost you $5 for the JB Weld, and the worst that will happen is it will blow out over time. With that much surface area that, I doubt it will though. It's kinda 1/2 assed yes, but done properly, the stuff is absolutely amazing . Get new heads if you can afford to, but for $5 you can't afford to not give it a try. Quote Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted February 20, 2004 Share Posted February 20, 2004 I doubt this car will be sticking around for long. Knowing Erik, he'll need to make room for another Erik, just get another block. No need messing around with this thing anymore, maybe take that 1/2 of the block and hang it in the garage to show off the damage -Brian Quote Link to comment Share on other sites More sharing options...
Subi81 Posted February 20, 2004 Share Posted February 20, 2004 I am wondering how the chunk got out of the engine or did you find it still in there. Either way that is wild, I have seen one inch long cracks in sleeves but what you have is a real keeper. Give it a proper burial, sorry man.

thealleyboy Posted February 20, 2004 Share Posted February 20, 2004 I duuno about JD Weld... Might work in certain applications, but I don't think I'd trust it for a critical seal in a "driver" type vehicle. If you are to that point, you need to bite the bullet and think replacement. It's not worth screwing with b*llsh*t when you consider that your labor is 90% of the job. If you screw up and it fails, then you're screwed. I would invest in a solid core to work with, or find a better car. Unfortunately, there is just no easy fix here. Good luck, John Quote Link to comment Share on other sites More sharing options...
Turbone Posted February 20, 2004 Share Posted February 20, 2004 :cornfuzz: :cornfuzz: :cornfuzz: :cornfuzz: Now how the he[[ did that happen? It actually looks like it was done on purpose. And I'm not saying Matt did it, it just looks man made. EA81 engines are all over. I know theres a couple in the Tacoma PAP right now. dont know what they charge for one tho.

clantieri Posted February 20, 2004 Share Posted February 20, 2004 Good point from alleyboy. He's right. Just do it right. The time spent in labor is not worth having to do it twice. Chris Quote Link to comment Share on other sites More sharing options...
bigjim5551212 Posted February 24, 2004 Share Posted February 24, 2004 You will not find a chunk. That is aluminum that has vaporized. We took a Chevy race car to the track 2000 miles away, drove it a few laps and the engine wouldnt run good. Tore the motor down and found the same as that picture. JB Weld is good for some things. maybe that problem. If you can find a good short block for $40 i would get that. Welding will cost a lot more, cuz then you need it machined.
