i dont get it man. w/e, i was driving the car last night in the rain and it started to act like the fuel pump was going. it would hesitate a lot, and it would rev weird. like while i was driving at a constant speed, the rpms would go down, then back up, down and back up until i mashed the floor... then it was ok... until i let go of the gas, and it would keep acting up. i turned the car off and back on, and it worked fine, but eventually went back to being retarded. then today it did it again, but started acting normal after driving it for a while.

now here's the best part. i started to notice i was smoking oil when i came across a cobra r and kept looking back to see how much i was pulling on him. i saw a cloud of smoke comming from the back. then i heard a metal clank, and the car died on me. pulled over to the side and it would only turn on if i gave it gas, and the moment i let go, it stopped. did that a few times till finally it stopped, and when i went to put it in park, the shifter was really smooth, it wouldnt grab onto any of the gears (this is a 700R4). i looked at the bottom of the car and there was a pool of what looked to be oil. wtf can this be? im going to take a look at it in the morning, but i dont know. maybe the rear main seal? i just had gears put in and i started to notice a humming noise comming from the rear, but i dont know if this has anything to do with it. i also noticed after the gears were put in, that the rear felt a little loose... like whenever i would come to a stop, i'd hear a clank comming from the drive train. anyone got any ideas on what to look for on the car to see if that's the problem? thanks for everything guys

 

I hope you have some money saved! Metal Clanks followed by the car dying are never good. Did the engine knock when you restarted it?

 

Sounds like you need a rebuilt trans. Think of it as a good reason to beef up your trans.

 

the tranny is a monstermotorsports 700r4.... with like 3k miles on it. POS. neverrr get a tranny from them, all ive had were problems.

and i really didn't feel any vibrations through the gas petal like i would if i had a loose rocker or something. it just sounded weird like if there was oil getting into the cylinders and being burnt... bro, i had to keep the gas down to keep it alive, and it was smokin' like cheech and chong's car - it looked hilarious lol

 

i think i figured out what happened to the tranny. dunno how but the linkage came off from the shifter underneath where the tranny is. i put the linkage back on and it shifts fine. wont start though. checked one of the plugs and, i swear, i've never seen plugs covered in so much oil in my life. im thinking maybe the intake manfold came loose again and started to suck up oil through the runners, or my blowby has gotten progressively worse within the matter of a day. i dont know. i still dont know why the bottom of the car would be covered in oil. oil pan, idler arms, headers and pretty much everything else under the car. thought it might be the rear main seal, but there's no oil on the converter at all. wtf could cause all the oil to go everywhere like that?

 

Excessive crankcase pressure will cause oil to blow all over like that, from every possible gap and seam. It would also explain the cloud of smoke under high load. The poor running and hard starting are likely due to the oil fouled plug(s). Unless you had a catasprophic failure of a piston dome, you may just be experiencing excessive blowby. The high crankcase pressure could have blown oil past a gasket (s) which would damage the gasket and explain the pool of oil after parking it.

I had a similar occurrence on my '67 Firebird 326, where at about 160K miles the blowby was getting to become a problem. One last hard run at about 80 in low with the Powerglide and one of the thin rings finally cracked and tipped in a land. One new block later it was back to running well. The ring had cut a groove almost .060" deep in a sidewall, and .120 oversize pistons were not an option.

You may have had a similar occurrence, or something different, but I'd suggest analyzing it before doing much more driving (and possible damage). A compression or cylinder leakage test would be a good start to help isolate the problem(s). If you're lucky, you only lost a gasket at the intake. A rear main seal likely wouldn't cause all those problems.

 

well, i think the blowby senerio might be close to what's going on... there was oil dripping out of the breather, and that's never happened before. the rings only have about 9k miles on them, so i don't know. i really don't want to do a rebuilt if that's the case i might as well go with a 383 and put my heads, cam and intake on her. how can my blowby be getting worse and worse if the rings are fairly new and i broke them in properly? u think that the intake comming loose and sucking in oil through the runners might cause the more blowby than i should be having? i gotta take the intake off and take it to a machine shop because i think the angel is off just a little. i notice some oil on the oil pan gasket, but i couldn't find anywhere under the car where oil would leak so bad it would pool on the pavement. there wasn't really any oil behind the block where the intake sits except for a slight leak that i've had due to the intake's angle being slightly off. starter was covered in oil, but the oil filter wasn't. thanks for the help vader, i appriciate it

 

If your rings are relatively fresh, that may not be the case. Unless you had some sort of mini-disaster, your intake theory might be valid. The lack of vacuum could explain the lack of adequate PCV and the oil therefore escaping. Since you know it's an issue, get that done and see what happens.

 

Yeah, thats what i plan on doing... i just need to figure out where the hell the oil was leaking from. if it was leaking from the oil pan gasket, do u think it would still leak if i don't replace it? where on the block would it be able to leak a niicceee amount of oil? enough to get all over the starter and all over underneath the car? oil pan right? man i really don't want to change the oil pan gasket, too, lol

 

well from what i'm hearing this could be caused by one thing that alot of ppl i know have taken off cause they think they'll get more horsepower, 3 letters man PCV, did you take it off? if not then check the hose for it, and the valve itself and don't just pickit up and rattle it cause the rattle don't mean jack ok your filter for the PCV might need to be replaced and those are like 50cents. what brought me to this conclusions what that u said your rear seal was blown and your oil pan was leaking and your valve covers were leaking, plus the fact that u mentioned blowby gases. ya i know this is text book crap but hey it helps in the field. oh and this might be bad but if you have alot of oil blowing by into your combustion chamber then it might be time for some new piston rings, or check the condition of your valve seals, guides,. I think ur linkage got mest up when u were driving in the rain maybe.

 

i have pcv on the pass side valve cover, and a breather in the driver side. reason being is that when i would put the intake manifold on the car with a new gasket, everything would run fine until about 100 miles, then it would be sucking in oil through the driver side pcv valve. my guess would be because the intake's angle is off and somehow the intake bolts untorque themselves, air is actually getting into the lifter valley and causing more blowby than usual. i never have blowby once i put the intake on with a fresh gasket. if i left the pcv valve on the driver side, i would be sucking up MAD oil
