Thanks,

 

The NO is a part of the cast when the manufactor the block, the numbers are stamped. Maybe its just a serial number?

So it should be possible to see the EA?? without taking anything off like the intake manifold?

 

yes and I would think it would be somewhere close to where those numbers were. It should be just to the left of the disty, and back a little. Or maybe towards the back near the bell housing. You don't need to remove anything to see it.

Ok thanks,

 

Man would you have any ideas of what kinda motor oil or something i could put in my motor to make it last a little longer/stop knocking?

 

I put a 20w50 in it bc i thought it would help with the knocking and it did a little but when she gets good and hot it starts sounding worse.

 

I started it yesterday and when shes good and cold the motor sound perfect. when the oil starts to get warm and seems to get thinner the knocking starts. But for the first 3 mins of running it, it sounds great, no strange noises. I also put some oil stabalizer call locus.

 

Im just thinking if i could run something that would be a litte thicker when it gets warm the knocking wouldnt start.

 

Any Ideas?

Your pic

It looks like an EA71 to me.

From the looks of the disty and your radiator,

it looks just like my 79' Brat.

Not to mention that engine looks by far smaller than the EA81 in my 85' Brat.

 

And your oil stabilizer, was that "lucas?" not locus?

That should help, but if you put too thick of oil in it the oil won't flow

enough to lube the entire engine at high RPM's.

The stabilizer I believe will make the oil stickier, more capable of lubricating

the engine and gears.

Hope it helps,

So I found a pic of the stamp that you should find on your motor, so here it is. Hope this helps

I found it!! To make a long story short i was driven my brat around friday and something started making a loud noise. Since the damn thing is already knockin i thought that it was just about to chuck that rod. So i figured what the hell, I jerked the motor out. It was very very simple.. Only took me about an hour and a half. Since i have a clue what Im doing i could probably do it in 45mins. Well come to find out some flat spring came apart on the pressure plate and was beating the crap out of the inside of the bell houlsing. but its still knocking. I pulled a motor out of another brat last night. Only concern is that it caught fire. lol. I dont think it got hot enough to do any damage to the block/crank/pistons. I will post some pics soon of whats going on. Oh and I have a EA71

So what is the motor that you pulled out of the other Brat? What year is the Brat? If it's a Gen 2 Brat you should grab the dual range tranny too!!

Its not a dual range. I looked. The motor is a ea71 and i think that the brat is a 1979-1981. Not too sure really but it has the same headlights that mine have. There is a 1979 brat out there with a ea71 that looks pretty good. But the guy giving me the stuff wants me to try this motor first. Its free so no compaints.

 

Do you thing the motor will be ok internally?

It should be, but it depends on how hot it really got around the motor. I would be on the search for a newer Brat with the EA81 and 4 spd dual range!!

Some day! are Cv shafts hard to change?

Not too bad. fairly self explanatory. You need a 36mm socket to fit the axle nut though.

cool thanks. i have done them on another fwd car before and it wasnt too bad. If i can find a 1982 brat or newer is it going to be a ea81?

It should be! 82-87 is when they were made and I believe all Gen 2 Brats were EA81

I was reading on enlighten me about ea71 and i dont want to steal his thread but whats the difference in the motors with the stamp by the oil fill neck or the one by the disty? besides what they are called? whats the difference?

 

Thanks.
