Need engine help I am stumped

[erickmarciano]

Hi guys was trying to help a friend who purchased. 280se coupe
The car did not start for 20 years
1-Cleared the gas tank  etc etc
2 - changed the head gasket and had the head rebuilt
Put oil for a while in the cylinder

We tried to start it and it will not
Did a compression test and only got 60 psi
Once I squirt oil I get 120
What should be my next step?
Thanks
Erick

It sound like you already spun it, so ....
You need fuel, spark, and air to make an engine run.
I would check to make sure you have those three.

Got all 3 but have a low compression would an engine start at 60 psi?
Is there a way to free the rings?
Thanks

Hello Erick,

60psi on all cylinders?

[erickmarciano]

Yes all cylinders
When I put oil I get 120-130
Thanks

I'd say that it's pooched.

You changed the head gasket ?, Low compression on all cylinders, Maybe the valve timing is out ?, Just thinking out loud,

[ctaylor738]

Agree with the Dr.  If you doubled the compression by squirting oil, it's hosed.

I am stumped with the words  "hosed" and "pooched".

Thanks for clarifying

I think they mean new rings/pistons, or worse, new block.  Regardless, it needs major work.  Ron

I think maybe slang has different meanings depending on where you live and in many cases it's local in context. Pooched is more commonly used around Toronto and seldom heard where I live.
Hosed has several different meanings. I've heard it used as '' getting hosed '' which means being cheated. Then there's '' hoser '' which is slang for being a Canadian, not in common use anymore. Hose head; a dumb ass. Hosey; trashy looking. Hose bag; a cheap tart who sits at the bar waiting for guys to buy her drinks. Hose; what you pee through. Hose; something women used to wear on their legs back in the 70's.

In this case ' hosed ' means; ruined, screwed, trashed, blowed up, beat, zonked, woofed it's cookies, puked, etc.

I could go on but that should be enough to demonstrate that there's more than one meaning.

Hello Everyone,

Erick has been helping me with this project, here are some missing information, according to the owner of the car the engine has original 43000 kilometers (European). The car sat for over 20, the work that I have done to the engine so far, taken the head out because of a couple of loose valve guides so I replace them all with new valve seals, the head had no bow to it at all very straight the rocker arms and the camshaft looked new, so my question is if an engine that is so clean with low mileage what are the chances of the piston rings setting back to original position if we are able to start the car with help of some oil on top of the pistons building up compression, has any body had this problem & was able to get it to work?

Thanks
Shaun

Hello Shaun,

Try to get it started. The rings may not be stuck that bad.  The engine heat cycles will help free them up. Make sure the engine is primed with fuel, you have a good strong battery and a fresh set of spark plugs.

What i found weird is when we were crancking the engine it would not turn very fast with a full battery. Are there different size starters that would turn faster?
Thanks
