some sort of internal leak?

Ok, to start off, I did a search for this symptom and found nothing. Basically, I have an internal oil leak I believe. I have oil on my spark plugs, and just changed the plugs to see if it would change anything... Nothing happened. Also my gas mileage has gone downt he crapper... I replaced the plugs with delco ones. If anyone knows what may be causing this, I will appreciate it very much

Re: some sort of internal leak?

Its a 92 blazer 4wd, I have kept it up to date on all mantenances. Like I just said, I replaced the plugs and gave it a tune up myself. Previously I had an alternator go bad, and had to replace a seal that goes to the remote oil installation under the truck. The smoke is more of a blackis whitish smoke

Re: some sort of internal leak?

included changing the spark plugs, changing the oil and the filter. checked the transmission fluid to make sure it was good. Pretty basic

Re: some sort of internal leak?

also, I was having problems before I did the tune up. That is why I changed the spark plugs, because I was having some idling problems

Re: some sort of internal leak?

What about:

1.) the fuel filter
2.) Air Filter
3.) PCV valve
4.) Timing check and adjustment.
5.) Distributor Cap & Rotor

Also, what gap did you gap the plugs to?

Re: some sort of internal leak?

well, I gapped the plugs to .o45 like the guy at autozone told me to gap them at, and I have checked any of those other filters, but even if I do change those would those affect the fact that their is an internal leak?

Re: some sort of internal leak?

also I know the air filter is good. the internal leak appears to be some kind of oil on the spark plugs I replaced

Re: some sort of internal leak?

The oil could have come from when you were removing the plugs and there was some oil in the plug holes in the block.

Did you do any of the other stuff I told you to replace ever?

A tuneup is not just plugs and an oil change.

Re: some sort of internal leak?

another thing I noticed is maybe the plug was not burning correctly. The top part of the plug where the prong is was white, but the rest of the part where it screws into the engine was black and had oil on it
