tjet Posted February 27, 2020 Share Posted February 27, 2020 (edited) Hey guys, I'm in the process of tearing down 1 of 2 ER27 engines. Here is my original post asking about ER27 info... I plan on getting the heads worked (3-angle, pocket port, & milled). The cams will be sent to Delta for a 260 dur "torque" grind. I want to do a leakdown test, but this engine is missing the balancer & bolt. Does anyone have a spare bolt or know the specs on it? I tried using an EJ22 bolt, but it's too small (diameter wise). I would take it from my other engine, but it's in California. This one is at my house in Connecticut. Thanks.

tjet Posted February 29, 2020 Author Share Posted February 29, 2020 So I did a leakdown test. All were reading close to this, except #5 cyl Quote Link to comment Share on other sites More sharing options...
tjet Posted February 29, 2020 Author Share Posted February 29, 2020 (edited) #5... All other cyls show cross hatch Edited February 29, 2020 by tjet Quote Link to comment Share on other sites More sharing options...
idosubaru Posted February 29, 2020 Share Posted February 29, 2020 I can’t tell what the photos of cyl 5 show? You probably know this but that engine has a warranty heat marker on it. It looks like it’s on the block so that block maybe has already been worked on before? Quote Link to comment Share on other sites More sharing options...
tjet Posted February 29, 2020 Author Share Posted February 29, 2020 (edited) Yeah i saw that. What is it for? Does the dealer put it on? It looks rusty in the #5 plug hole. I will pull the head in a few days & get some pics. here's that tag Edited February 29, 2020 by tjet Quote Link to comment Share on other sites More sharing options...
Steptoe Posted March 1, 2020 Share Posted March 1, 2020 (edited) Wreckers have used these discreetly on used engines they supply in case of any warranty claims. Engine rebuilders also. Got a stash of these somewhere. The centre of the washer is like solder, if not solder. At certain temps it melts and falls out leaving tell tale sign the engine has been cooked. I failed to measure temp as it melted when I warmed one up on the furnace So where was the leakdown leaking? Could you hear it in intake, exhaust or crankcase?

Seemed like the air was escaping thru the crankcase. I have the oil pan off, so it's not like I'm getting a stream of air from the oil fill. I will pull the head to investigate further. It's weird that the tag thing was glued right over the bad cylinder. Maybe just a coincidence. If I had to make a guess, the head gasket had a leak, which allows water to fill the cylinder while it was in storage.

tjet Posted March 1, 2020 Author Share Posted March 1, 2020 (edited) So it appears that the engine leaked water into the #5 cylinder during storage this rusted the lower section of the cyl wall. The good news is that this engine has 5 head bolts per cylinder and a closed deck. How cool is that? . I think an EZ30 only uses 4 head bolts per cylinder.

tjet Posted March 1, 2020 Author Share Posted March 1, 2020 The head shows the same evidence Quote Link to comment Share on other sites More sharing options...
tjet Posted March 1, 2020 Author Share Posted March 1, 2020 Head gasket looks ok, too. The part # is 899235, and it was made by Nike Quote Link to comment Share on other sites More sharing options...
tjet Posted March 1, 2020 Author Share Posted March 1, 2020 (edited) It looks like the max bore limit is .020", So the factory bore is 3.620" + 020 = 3.640" ...Woohoo. I hope it will clean up. Edited March 1, 2020 by tjet Quote Link to comment Share on other sites More sharing options...
el_freddo Posted March 2, 2020 Share Posted March 2, 2020 Made by Nike! I love it. That’s actually the Fuji heavy industries logo, they’re the parent company or something that owns Subaru I believe. The EA82 was closed deck too. It didn’t do much for the cooling system, and any strength gained wasn’t worth it really. Pretty cool looking engine though. Are the exhaust ports singles or Siamese and a single? Cheers Bennie Quote Link to comment Share on other sites More sharing options...
tjet Posted March 3, 2020 Author Share Posted March 3, 2020 I wonder if they are factory installed gaskets (like if the heads were never removed) 2 cylinder share 1 exhaust, and 1 is separate. Quote Link to comment Share on other sites More sharing options...

jdmleggy97 Posted March 3, 2020 Share Posted March 3, 2020 Did a 3 angle valve job, cleaned up the ports on the intake/exhaust, and milled down the heads a bit on my ER in high school. The power was nice! Lost a few upper RPM in the rev range but I can’t say at all that the engine didn’t wake up lol Didnt last very long though. I used the wrong silicone for the cam carriers/housings (I just didn’t know. I was a kid) and it broke down into chunks and clogged up the oil pickup.

I've seen a couple big closed-deck EJ22t cars that required so much more cooling capacity than it seemed similar semi-closed blocks required.

DaveT Posted March 3, 2020 Share Posted March 3, 2020 What does closed deck vs open deck mean? I haven't seen this terminology used before. Quote Link to comment Share on other sites More sharing options...

This is a swap project, and I can install a large radiator and an oil cooler if needed. 6 hours ago, jdmleggy97 said: Did a 3 angle valve job, cleaned up the ports on the intake/exhaust, and milled down the heads a bit on my ER in high school.

This is very common discussion with performance EJ block selection, as all 3 forms are available 33 minutes ago, tjet said: How much more cooling capacity does it need? This is a swap project, and I can install a large radiator and an oil cooler if needed. No easy answer to that without some serious thermodynamics engineering. And being that yours isn't going in a Subaru, airflow will be all different from most of the documentation. But the EA/ER engines have very weak cooling systems, heat will probably be your biggest challenge, depending how hard you try to push it. Err on the side of caution with radiator capacity, oil cooler (at least oil/coolant exchanger, oil/air can be hard to prevent overcooling) would likely be a good idea. A radiator that struggles to keep a 90hp EA82 cool can keep a 130hp EJ cool without any fans. Don't run a lower temp thermostat, though. Aluminum engines don't like being run cold, either. But if you've got adequate cooling capacity, you shouldn't go over "fully open" temp on the stat. 1 Quote Link to comment Share on other sites More sharing options...

The radiators on these old VW vans are very big - almost overkill. I added an old cooler with it's own fan a couple of years ago. I also removed the AC condenser in front of the radiator.

tjet Posted March 4, 2020 Author Share Posted March 4, 2020 Quick question: On this ER27, I've noticed various ports and nipples on the intake manifold, engine case, and valve covers. These are for water, vacuum, oil and breather. I would like to know what I can eliminate on this engine. Quote Link to comment Share on other sites More sharing options...
