HI, some mechanics rebuilded my 302, (.030) we installed a comp cams 282 solid lifter cam, 1969 302 chevy valved ported heads, (9.8 compression) offehausser turbo trust tunnel ram (single carb) (edelbrock 650 mech), (msd), like two months ago, but the valve cover breathers are SMOKING more than normal,(from first day) you can see the smoke coming out from the hole in the hood when driving, the mechanics say that is normal, that once the rings settle down it will go away, but it has 2 months and it didnt go. they said that i can fix it whit some pcv sistem to the headers. the engine runs good, the only think is the smoke and some kind of knock sound inside the engine, i think its because of the solid lifters, the mechanics told me that the sound is coming from the transmission bellhousing (t-5) but i think thats bull **** they said that theres no problem, that i can race the car like that and if the engine broke out, they will fix another for free. so my questions are, is it really normal the smoke? and the knock sound?
i would think there is not supposed to be enough smoke coming out that you can see it coming from the hood. as for the sound solid lifters are a little noisier but it shouldn't be too much noise. if so they need to be adjusted. there should not be a noise coming from the bellhousing in my opinion.
Engines will have some blow by without a PVC system but it should be very little and not be as thick as you say it is. I have no PVC system on mine and mine does not smoke at all. As far as the knocking sound, hard to say without hearing it but it should not be making any knocking sounds. Solid lifters make more of a rattling sound.
I know its not a ford, but one time I was sitting in traffic with my 307 olds and the pvc hose cracked off. The only reason I knew that happened is because there was alot smoke coming up between the hood and fender. If your not running a pvc system i can imagine some smoke. I cant say that motor was in the best running condition though, I blew the oil pump and froze it up on the freeway about a month later. I also know a guy with a '62 caddy that has about the same problem too, no pvc there either.
I had push-in breathers in my car at first. The only timeit smoked was when I was twisting the heck out of it and the breathers got soaked with oil, and were dripping on the headers. I have since then put a remote breather set up on it. That may be something to look at. Also, solid lifters will make more noise.
You should always run some form of active crankcase vent. Your rings will last longer!!!! Gulupo I would say in my professional opinion: You got a bad motor, with bad rings, and probably a bad thrust bearing ( maybe all the lower bearings are loose/bad) Your engine needs to be rebuilt by someone that knows what they are doing.
but if the rings wrong, isnt it supossed to be smoking tru the tailpipes two? no smoke coming out the mufflers..

As was said before. There should be minimal smoke (blowby) comming out of the valve covers. If the rings have not seated in 2 months they are not going to. There is a problem with the engine. I have seen this one time before. I looked at an engine the a guy built and it was doing the same thing. Fresh rebuild and all. I tore the engine down and found the rings had been installed upside down. You have a problem and the guys that built the engine need to make it right. As for the knocking noise comming from the bell housing on a clutch car,,,,,,, probably not the clutch assembly. I would have to go with the thrust barring also. Was the engine built by a shop that is in the busness of rebuilding engines or was it Joe Bob and Cooter out back of the barn? From what you have said they have your money for the rebuild and they want to convence you that it is good to go no matter what the engine is doing. When I build a performance engine for someone I tell them straight up front that is has no warrente(SP). But that is for broken parts after they get the car on the road (because I know just like they do that they are going to take it out and run the pi$$ out of it the first chance they get). This is a problem that has existed from the time it was assembled, they need to fix it. Something is not right, rings not seated is no excuse for the problem you are having.
