Boosted GS-R
running 10psi
Idle has a real stutter to it.
No oil in coolant or visa verse.
Not burning oil.
No smoke from tail pipe at WOT
just a crap *** idle and CRAPPY compression results.

CYL 1: 230
CYL 2: 225
CYL 3: 75
CYL 4: 180

Thinkin maybe ringlands
Blown HG, no idea what do you guys think?

 

bent valve maybe....Leakdown time.

 

i highly highly highly doubt its the valves.
but thanks for the suggestion.
back to the top either way

 

dont highly highly doubt anything.....The world can burn at the flick of a switch, dont forget that....

 

bump, subscribing to this one.

 

Try a leakdown test and see how much the results vary. That'll tell you if your ringlands are shot.

 

Does it iddles like if you had a big cam on it? very lopey?..If so then i think ur #3 piston is trashed.

 

to loose that much compressiom u either have bent valves or blown rings
or headgasket blown between #3 & #4

if it idles like **** but runs kinda OK then u defenetly have bent valves

like someone said
just get the leakdown done

 

you know i'd love to get a leakdown done, funny thing is know one around here does them! so how does one do a leakdown or what tools are needed and i'll grab em

 

air compressor leak down tester and thats all you would need to do a leak down test. The testers you can get at most auto parts stores. or online.

 

Tavia makes a good leakdown tester, that's what I've got.

 

Just put a teaspoon of oil in #3 cyl. If you get higher compression then you know it's piston related.

 

i'll be trying to grab a tester today i'll keep yall posted

 

#3 usually detonates first, my vote is for cracked ringland/rings.

 

Just take the head off and look. Don't waste time or money with theories.

The car runs like ****, just take it off. I am sure the problem will be obvious.

You have to fix it anyway.

What immortal time wasters.

Bump I'm curious to see what happened.
