What should be my next steps????

 

Do cylinder leak down tests to pinpoint where compression is lost. My guess would be a bad head gasket with two adjacent bad cylinders.

 

hmmm need to get my hands on leak down tester and air compressor

 

UPDATE: did oil change -which was super gross oil.. change the spark plugs did another compression test

I think anything above 180 is good to go correct?
Pretty weird what a little freshin up can do!

 

That looks much better but the same 2 cylinders are still suspect. If it were me I wouldn't stop there. Did you do a leakdown test?

 

na no leak down test yet.. I'm thinking it might be the valves

 

Did you do a wet compression test ?
Or dry ?

If not, try a wet test in #2 and 3 cylinders...
If compression rises, you need compression rings...

If not then continue with any other suggestions.
Hope everything works out.

 

whats a wet compression test.. im guessing i did a dry one

 

poor some oil into each cylinder before the compression test.

 

here silky chemical leakdown tester

when you use it if the chemical turns a different color youll know if your headgasket is blown its somewhat pricey but they do work

 

what engine is this? if its a b7 i'll defiently say headgasket being that the b7 is known for poor cooling efficiency between cylinders 2 and 3

Is your exhaust manifold cracked in the center?

Thats how my Dads D16 lost 2 exhaust valves on the highway. (in #2 and 3) Tho I bet its the gasket too..

Also, I think I got my LDT from Harbor Freight, for a couple 20s.

 

Drip a little oil into those 2 and re-test. Do it right before you test it.
