SVO Help

Engineer101 · November 13th, 2008, 01:12 AM

Hey, guys I've got a friend you needs some help diagnosing his SVO.
It's an '86 and he has been running 18 to 19 lbs on average.
From what he has told me there is oil and gas leaking and maybe some coolant, not sure on that part because he wasn't clear.
We figure it is most likely some sort of gasket or other seal.
One other friend of his says maybe a leaky injector. The only other guess that we have is the head gasket because of the forced induction.
I'm not really familiar with SVO's just the basics, so any ideas that you guys have I would really appreciate.
Thanks.

I too had a coolant leak. I checked the hoses and it was torn in one area. Replaced it and now it doesn't leak anymore. I thought it was a bad head gasket too because I thought coolant had leaked inside the engine. Does his SVO exhaust come out as white smoke? Also do a compression check and back with the results for possible burning coolant. I'll try to get the specs.

I'm not sure whether he has checked the hoses, but he still said there was gas leaking too whether they were mixed or not I don't know.
I don't know about smoke though he didn't say anything about.
I didn't think about a compression test, thanks.

first off, where is the leak coming from?

back of head, back of block, thermostat area..?

i know its not yours, but more information is really needed to know for sure

rear main seal possibly, head gasket possibly,

fuel in it..how could that happen lol. sounds like a few places are leaking if thats the case. is it for sure fuel, or is it just oil residue.
