I got about 2k miles on it right now after having a super bad blowby problem! Now today i smelled something funny so i decided to pull over and check the engine.

I noticed a little oil on the oil dipstick handle and became very worried becuase thats what the engine did before when i had blowby real bad.

I pull out the dipstick tube while its running and no smoke is puffing out at all so im starting to feel better and just to be sure i decide to rev it a little bit just to see and when i rev it up sure enough a little puff of smoke comes out from the dipstick tube but then it stop's?

I then put the dipstick back into the tube and unscrew the oil filler cap fearing the worst! But no smoke is puffing out of the tube while she is running! I give her a quick rev and sure enough a little smoke puff's out from the oil filler tube but goes right away. Seems the higher i rev her the more smoke will puff out but it is not a steady stream of smoke like last time just a quick puff and then nothing.

Now my question is what is considered normal blowby? Is this anything to be worried about?

When i first got my car back from the shop i was easy on the engine for a 100miles then i put her in second and wound out second gear and then let her engine brake back down to around 40mph did that a couple time and have driven her normal since.

 

I have a flow, but not enough to pop the stick out.

 

Have you checked the PCV valve to make sure its working?

 

Think about a leakdown test.

 

Holy crap something is leaking from behind the rear left hand side valve cover onto the exhuast pipe and then smokes real bad!

It does it after i rev the car up and it returns to idle. Look's like i may be replacing an intake gasket?

 

You need to find out why you apparently have excess pressure in the crankcase. Too much blowby will cause pressure to build up, but it takes an awful lot of blowby, since the stock system is designed to relieve the crankcase pressure through the air supply line from the throttle body to the passenger side valve cover. Pull that line off and look for excessive oil buildup. Pop the cover on top of the throttle body, and look for a puddle of oil. That would confirm excessive blowby. Of course it could also be the result of a faulty PCV valve, but apparently you don't want to check that.

 

There is no blowby it's just a fine mist that floats from the oil fill tube when i rev it up to around 3k rpm's and above that is why i asked if that was normal. I now know that all car's do that to one degree or another.

The smell was coming becuase the rear intake manifold was leaking onto the exhuast pipe and smoking pretty bad. It only leaks when the car gets revved up ive felt back behind the manifold and sure enough there is a tad bit of oil seeping through.

 

Damn this is just so heart breaking to me i love this car but all the problems its giving me is making me feel as if it will never run reliably

I can pop the hood with it running and it has a very bad rough idle now with a check engine light and i can tell it ethier has a very bad vacumm leak or its missing. I can stand in front of the car with it running and i can see alot of smoke rising up from the back of the motor but i cannot see any oil actually leaking it's very frustrating! I know for a fact the oil is burning on the exhuast pipe at the rear of the engine. If i get into the car and drive it it run's normal and rives smooth and everything it is only at idle when it has a rough idle problem. At wot is when the oil leaks the most and will spray all over the back left hand side of the engine covering the rear portion of the valve cover and soaking the passenger side header.

Im soo lost i have a feeling its the intake manifold leaking as it is wet with oil back there but the rough idle has me stumped could a leaking intake manifold cause a rough idle on these cars?

 

Can you give a little more info about the recent rebuild? Just curious who built it, what was done and do you know what kind of gaskets was used?

 

Have you checked to make sure that your passenger side valve cover is correctly seated to the head? It can appear on there and not actually be completeley on. This could put some oil on the header.

 

Well this morning i decided to check the pcv system for leaks or problems i started at the pcv valve and followed the hose to the front of the trottlebody and to my amazment the hose was not attached to anything! Right there i decided to remove the throttle body and upon further inspection found that the whole pcv system was leaking or not working due to cracked leaking or disconnected lines!

Went to the hardware store bought a new pcv valve hoses and some clamp's. I replaced every hose on the whole top of the engine taking special care to use clamps where needed and to route them so it looked clean and tidy.

Even took the TB apart being carefull not to mess with the iac valve and soaked it in carb cleaner and then scrubbed it clean i noticed my air foil was blocking the majority of passage the top of the TB used by the passenger side valve cover breather so i removed it for extra clearance.

Replaced my old serpentine belt with a nice gator back and put everything back together!

Fired her up and ohh she idled so good no check engine light no miss and most important no smoke or oil!

I guess i was the victim of total pcv system failure! Geeze i feel so much better now i even looked at another car just in case it was the rings or something.

Thanks everyone for the insight and help!

 

Cool..... That was an easy fix.
