Dead Piston - what next

Featured Replies

I'm stuck between a rock and a hard place on this one. Just found out that the subaru i bought has a dead piston.

 

I have 4 options I'm looking at.

 

1. Rebuild

 

2. Find a rebuilt ea71 to put in it.

 

3. Replace the ea 71 with an ea 81

 

4. Sell the car.

 

The body is in great shape . no rust. Everything else works great. Getting psi in the 90's with the three other pistons and 0 on the other one.

 

 

Its an 80 DL 1600 Hatch 4wd .... what you you guys do?

1. Rebuild

 

Or at least pull it apart & see what the problem is. It could be nothing more than a sticking valve.

That is true ... would a sticking valve cause blowby?

umm prolly just the rings, how many miles does it have on it?

52k

 

 

Would bad rings cause a dead cylinder?

Id sell the engine out of my 80 GL Wagon, 1600 just like yours. It was rebuilt around 75K ago and runs great. Id like $250 exchange for it. You pay shipping to me and I pay shipping to you. Use the pallet that I ship you yours on for return. If interested email me. Will include disty, carb, alt, etc...COMPLETE.

Why didn't the mechanic who diagnosed this

 

perform a leak down test?

 

That is one

B-U-Tit-Full

 

Hatch.

 

Ya can't beat

Shawn's offer

 

shipping might be

more than the cost

of the

lump.

 

then sounds like

you will have to

pay to

have it

installed.

 

clutch and pp

ect

 

you puttin' away

a grand to finish this

project?

 

what will it be

worth to you

when your are

done?

 

I am a simple man

I tend to look at life

the same way.

 

Good luck

may the

Power of the Pleiades

be with

you.

I'm going to get a second opinion on it before I do anything really ... just checking into my options. It hasn't cost me anything yet. I've had friends look at it.

TS,

You did ask -- what's next?

 

I guess what I am trying to say is the phrase

 

"Dead Piston"

 

Is a bit

nebulous.

 

0 psi could mean several things

but the only way I know to come up

with a bagel in the comp

test is

 

1) a valve hung wide open

 

2) a big hole in the piston

 

Both of which are rare.

 

#2 would cause blowby of the 10th degree

So much it could blow seals out of the block

 

If you removed the oil fill cap (I see it's been replaced)

the

"huffin' "

coming out would astound you.

 

 

Please request a leak down test.

Then you will know where

the problem lies.

 

As I said

very nice car, good luck.

Yes, the sound is very noticeable comming out of the filler cap. I'll see if we can do a leakdown before i take it to the second mechanic.
