Blow by nightmare

Her's the deal...

Newbie 3rd gen accord lx-i owner
purchased in n.y. for 500$ from an auction
drove down to miami no-prob
car would sputer at around 4000 r.p.m. and blow out smoke from tail
then would leak oil like a M***** F***** all night...
through another forum found out might be clogged pcv causing pressure in crankcase to blow oil from seals...
next nightmare was finding pcv and pcv box...found it and broke hose where it joins at pcv breather box...soooooooooo.........spent 1000$ for entire exaust system front to back which it needed anyway due to salt and water rust out from north...
but before doing that repair (and not minding exaust fumes flowing into car cabin from engine and not to mention embarrissing at stop lights) car ran super i mean i got it to 110 mph no sputter nothing no oil leak clean...
o.k. back to repair no more fumes engine quiet now no exaust sounds but whallah sputter, blow by from pcv hose, oil smoke from exaust(alot after 70 m.p.h.), oil residue in exaust piping and of course the oil leaks when car sitting off

W>T>F> happened checked pcv and it is clean as a whistle changed it again just for the hell of it and still problem what is going on here..

i love this car and want to restore it to its original splendor but man im goin through oil like nothin...help...

that sucks man i dont know what to tell you

it is a possibility that you might have an internal oil leak in your engine. oil is getting into the combustion chambers and therefore you have that blue smoke flying out of your exhaust. piston o-rings can be suspect as well. do you know where the external leak is at?

I think your problem is a hole in a piston. Do a compression check. I had this problem a couple of years ago on an 87 LX. Pulled the head and did not see damage on the piston. Pulled the piston and the darned thing had a broken ring and a chunk of the piston broken between the rings. Installed a used piston ($6) from the junk yard and the engine is still running good.

Had the same problem last year on an 87 LXi. Fortunately, when I went to the junk yard the first time, I picked up two pistons. The book called for a different piston on the LXi, but I stuck in the LX piston anyway. Engine is still running good.

Both cars had serious blowby before the repair. The LX had oil all over the air filter and the LXi poured smoke out the tailpipe.

With the LX, I pulled the head completely off, removed all the pistons, and honed the cylinders and installed a new head gasket. The LXi was one step away from the graveyard anyway, so I just raised the head far enough to slip the old piston out and the new one in. Slapped the engine back together and got lucky.
