The EA82T HATE wall

Gannon · Post by **Gannon** » Tue Jan 19, 2010 8:21 pm

As for italics, there is a slanty I at the top of the reply box in between the B and the U

I was thinking today, imagine getting an EA81, putting on the SUB4 heads, then adding a turbo and intercooler, like we do to our EA82T's. These heads should make big hp numbers easier than with a normal EA81T/82T

There ya go Jono, EA81 with SUB4 heads and turbo and LPG for the brumby

Control "I", or use vb code with [ i ] and to finish the italics [ / i ] without the spaces between them

The cambelts - its kinda funny but I forget the EJ has one, where as the EA82 I was for some reason conscious of the timing belts being there. Its weird and probabily just me

The EJ belt is twice the width of the EA belts too, probabily a little longer if you cut and joined both of the EA belts...

Might have to jot that down. Not in here in the quick reply box. Funny how I am venturing outside my safety zone of technology. Cut my teeth on old two stroke Victas, still hate four stroke mowers yet Unc and brother swear by their well maintained ones 15, 20 years later, then points dizzies, one cam Falcon sixes, Mazda OHC still with points, revert to cam in block simple EA81's then went the whole hog with the GLTM, straight to turbo mpfi and timing belts. so, that's it eh?

Get some decent numbers going for Lotto boys and I just might

I still gotta git an AWD box to play with...... when I hit wet days I want AWD. When I lose traction on dry take off, over bumps - I want AWD.

I also would not mind chatting to Miss May of the 2010 Wurth calendar

We have no idea what you are talking about till you post some pictures

Working on the pictures. Might have to take up a paid job taking pics of pretty womans. There IS another story there....

Just on the other side of the wall to this HUGE calendar is a car wholesaler of 15 years trade who paid an interset in my GLTM - "Is that a 4WD?" In truth , that is what it said on the door he was looking at, even though it was matching red, the door was off my other GLTA. Fifteen years in his business and he did not know the L Series came out in turbo. Took him for a bit of a BLAT up the road. he was impressed - another convert? No - he likes his little Mira like cars that give him about the same costwise transport as my EA82T on LPG. Maybe we could get him into a Sherpa or Fiori for starters...

scroll down to find someone sold one of these calendars on ebay for $50

The rep actually swapped last years for new this years.

just adding to the hate wall.

me ea82t has finally had it. an over heating experience or 3 didnt help. this morning when i looked inside cylinder 1, there was about 1cm of coolant in the bottom

so that engine is coming out....NA mpfi with added turbo goodness here i come - earlier than expected

you just wanted that to happen to give the project a kick start !

Struck a snag with mine - bridge crack all the way through on the RHS head, at least got my EA82T modded MY cross member in the Brumby.

ROFLOMA - Nice way to start a war. Good topic drag out some of the ol hardcore school and still supporting the 82T.
Oh and for the uninitiated or just so my contribution is on record...

I also HATE the fact that i LOVE the lil EA82T 4 banger

kama/calmer . Today is going to be a good day regardless of if Ellie runs or not . Step one is to make sure compression tester works properly .

Ya know, Brettys Wurth calender is still on May 2010 !

The problem according to the test gauge is low cranking compression on all four pots , it varies between about 55 and 12.5 pounds so no wonder the old basket won't fire .
The $64 question is where to go from here . Coxy reckons give it another dose of Subaru bug and engine killer and see if that clears any more gunge out . I think the go may be directly down the plug holes this time .
My concern is how to bleed down the hydraulic rocker pivots (HVLAs) or if they just do it themselves . The factory manual only tells you how to test them when out on the bench .
Just for the record if I have to remove the cam covers how messy is this likely to be given that the engine has not been run for 1 1/2 weeks though its been cranked over a fair bit .
Again not going to have much time for a few days to do too much with this car .

gut wrenching discovery

compression loss expected at the valves ? surely still down inlet TB, compressed air down same while cranking. Reckon HVLA's will bleed down on their own.

If excess oil in cam covers worries you jack up on left and leave drain, repeat for right

There is no way to manually bleed the HLAs, removing the cam covers will not help you apart from taking them all out and compressing them in a very strong vice or under a shop press or flicking the caps off them, dissmantling them and re-assembling them dry. They bleed down on their own (eventually)by either oil leaking back past the ball valve, or past the piston, which of course happens faster when the oil is hot.

If you do pull the covers, what I find works well is get about 700mm of kitchen al. foil and fold it a couple of times, then feed it on top of the header, under the cam box, fold it over the edge of the crossmember and shape the rest so it has a slight fall and aim the low point into a container on the floor. Foil is easy to shape, cheap and if you dont tear it it will catch any oil and solvent you drop down and run it into a container.

Foils not a bad idea to keep things from getting too messy .
The idea of removing the cam covers is to see exactly wherethe valve stems are in relation to the cam lobes .
I'll ring Paul tomorrow to see what he did to free up the sticking valves on the EJ engine that did this to him . I think he may have given them a bit of a rap with something solid but not hard to try and jolt them free .

Being new to the forum and to Subaru's it has been interesting to read about the problems and issues with the different motors. my very first encounter with a Subaru was one of the mates a picked one up cheap a early model sedan one of the square shaped one, seemed to go well until we stopped for petrol he went to start it and found out it had done a head gasket. so dropped the water out off the radiator removed the spark plugs turn the motor over to remove the water from the cylinders then start the car fill the radiator and drove home only about 10k away. so after that i didn't think about the subarus again until now owning a 1990 brumby that is just sitting their waiting for more parts and funds to bring her back to life. I was just wondering with the motors being change over time if any of the components are interchangeable say like they do with the mazda rotary motors fitting this part and that one to make a better running stronger engine and what's the difference between long and short blocks

That really deserves its own thread but its subjective because what should have been done was in later EJ engines .

To go there briefly the EA81s were good because they were light compact and relatively simple things - for a flat four .
The EA82s tried to go forward by ditching the gear driven in block cam and pushrods by using cambox style over head cams on each bank .
Then they had to add two staggered timing belts and bulky covers to keep all the bitey bits contained .
All they had to do was come up with a pushrod system that allowed better ports than garden variety EA81s had and it would have been MUCH simpler than the EA82 debacle .
I think all you could possibly interchange is rods and pistons - maybe , though I don't know if theres any advantage in doing this .

What you'll probably find is that it's little bits of carbon that are jammed in the between the valve seats and the valves not allowing the valves to close properly.

I don't know what the fix is for this but I've just remembered that this is pretty common in the flat fours. The trick is probably to get it started or to tow it around trying to start it while hoping the valves clear up and start doing their thing again.

It's painful! I hope you find an easy way to resolve the issue.
