Compression issue...

Allright well i just got back from Texas, and now i need to get the coupe up and running, for a trip down there and i mean soon...
Well here is my problem, I have and S13 sr, basic mods, FMIC, 3in exhaust, nothing to big...
Before i left i was doing some routine maintanance, and i realized that there was a milky residue under the oil cap, so i decided to do a compression test and i got 120-60-120-120, i think its the head gasket, since its mixing oil and coolant, but if anyone could provide a second opinion that would be great, since im gonna start to take it apart tomorrow..

sounds like a HG, like you said. compression numbers are also a little low, most likely due to an old engine though.

Thats what i thought Kevin, i also wanted to do the piston rings, but im a little short on time...
I think im gonna do a Cometic HG since i could pick it up locally from TF and ive heard good things about them...

its your head gasket for sure but i would also think of changing the rings well your at it.. you never know when they might go and then you gotta rip apart the engine again...

just something i would do...

dont forget to check the block for being flat.

yea you dont want the head to be warped..if you have time. take it to napa. and have they hot tank it and get it decked.. its only like $100 or so.
its worth it so you get a good seal on the block.
and as for the milky-ness dont drive it anymore. change out the oil like 4 times. and have it run for 5-10 mins and change it.
till its golden

Napa does that, i had no idea, i do want to do the ring's but im a bit pressed for time.
Ive stopped driving the car as soon as i seen the milky crap, but it didnt over heat or anything so i think the head should be in good condition.

where you going trucky?

My dad is starting a business down in land O'Texas, with his brother, so im going down there with him..just for a couple of weeks though, since the boy trucky is hella unemployed...

your compression sounds ok but low on one and was the shit on the oil cap cuz if it is thata not a problem unless its in the oil then your screwed but if its just on the cap i forgot what its called but my auto teacher was talking about that a few days ago and says that its just resdue not a problem

check your oil is your dip stick milky

Shit the head is already of the block, and im taking it to a machine shop so they could check the head out, if it turns out to be in good working order, im going to do the rings...and then put every thing back together...

Compression is low across the board, my SR had 165 in all 4 cylinders so it is most likely your headgasket as people have said unless you have fried rings in all 4 cylinders [god forbid lol]
