1995 Accord V6 2.7 - Exhaust Smoke - Honda Forum / Acura Forum

1995 Accord V6 2.7 - Exhaust Smoke. High miles. I had the compression checked and all cylinders were 165. I was told not a blown head gasket. It is light white smoke that really doesn't smell like oil though or antifreeze. If the car sits for a day or two without driving it is really bad then it clears up to almost no smoke, but if it is driven daily then it is still a little bit and clears up even more at high rpm. I have been told everything from rings to valve stem seals. Anybody have any suggestions or anything I can look at before I decide to tear into it? It is also leaking at the bottom of the timing belt cover as I will probably do that over the weekend..All is appreciated

white smoke = antifreeze or just moisture in the exhaust.

burning oil = blue

OK what is the absolute 100% certain way to test for a blown head gasket?

i would use a liquid head gasket tester.

this is what our shop uses(i just bought my own)

this is the best way to check for a blown head gasket.

do you know of any parts stores that carry these?

HondatechAV6 · 11-01-2007, 09:18 PM

well, you can buy the fluid from carquest, try them. give them a ring.

well it is not a blown head gasket..So my next thought leads me to the valve stem seals or worn rings...If they rings were worn though would the compression below? It is 165 on all cylinders? How tough is replacing the valve stem seals? Or could I have good compression just getting blow by on the oil ring?

is the engine noisy when reving it in park? like a roaring sound or a growling sound? either way, i'd consider just getting a known good used engine.

No that is the weird part. It is quite as can be. No noise what so ever. Even at high rpm's while revving it up in P. used 2.7 engines are hard to find that are under $1000. What do you know about the C27A1 2.7 that came in the acura legend will those work? I have heard they will with changing the exhaust manifolds...

but then doing rings and valve stem seals would cost about the same as a used engine.

HondatechAV6 · 11-14-2007, 05:21 PM

but if the valve stem guides are messed up seals won't fix that. it's up to you.

i'm not sure if the acura will bolt in or not, anyone else know?
