Ok I just had a good friend of mine who is also a proffesional mechanic, replace the intake manifold gasket , and EGR solenoid and solenoid wiring harness. And I asked him to advance the timing a few degrees. He says that he advanced it 2 degrees. But now my car doesnt seem to have that same speed. Its still quick, but it wont spin the tires from a stop anymore, and it just doenst move like it used to. Is it possible that the advance is too much.

It is possible that its advanced to far and causing the knock sensor to retard the timing, but 2 degrees usually wont do that. Did he unplug the est wire while setting timing? Its very difficult to get an accurate reading with it pluged in.

Did he plug the EST wire back in?

Could be too much timing now and you're getting knock, and the sensor is pulling out timing.

Or you could have a vacuum leak now.

Yeah any of those...basically check over everything he touched. Does your brake pedal feel any different, any fading or a little harder than usual? Major vacuum leaks can be felt through the brakes sometimes. I'd definitely check into the timing...sounds like for some reason it's being retarded not advanced. Does the car seem to start up real quick and idle maybe 50 or 100 rpms below what it used to?

Yea its starts up faster , and idles lower, and on top of all of that , I dont **** for oil pressure ,it used to be around 30-50 , now at idle its at 0 and it barely ever gets to 30.

Rob Wade

Is the distributer in right??? No oil pressure means the pump isn't connected to the dizz, I'm thinkin! Sorry my bad, you do have oil pressure.

if it starts faster and idles lower, I think that's a sign the timing was retarted, rather then advanced.

cheese_kake

Really, but I hope that he didnt screw up soo bad that he retarded it instead of advancing it, oh well I guess Im gonna have to have him look at it monday. Another thing the exhaust is louder at idle , and it sounds more lopey, but he did clean out some gunk when he replaced the intake manifold gaske, so I dunno whats going on. Go messing with the timing make the exhaust sound different, or could the lower idle just make it sound differen??

Nixon1

Sounds like your timing is definitely retarded, you got all the tell-tale signs. Figure out that oil pressure though...verify with a manual gauge not electric if possible. Nothing he did should have affected your oil pressure. Does the motor knock at idle esp when cold...or is there a lot of valvetrain clatter? Oil pressure that low, if thats correct, will hurt the motor real good real fast, esp if you rev it out at all

cheese_kake

Ya I didnt think anything he did could have affected the oil pressure. All I know is it had good oil pressure before I brought it in. So hes going to have to find out what happened. But I also just thought that possibly it had more advance before he worked on it. I've never changed the timing before so its possible it had more advance and that when he changed it. It's now lower.

Nixon1

But if he RETARDED it from where it was, wouldn't he have told you that, or asked you first?

I hope he knows about the EST connector....

cheese_kake

I hope he does too. I have to ask him about that.

BackInBlack86

unless he didnt know the difference. unfortunately, any monkey with a toolbox can get a job working on cars professionally, all you need is a good line of BS.

Nixon1

Sad but true

cheese_kake

OK so I brought it back to him and we re-did the timing. He forgot to disconnect the EST and didnt tighten the distrubtor hold down bolt and it had dropped the timing 6*!!!!!!. So we brought it back to base and then advaced it 10*. The engine is perfect right now , and after giving it a run on the *** dyno its alot faster than it was before I had any work done to it. As for the oil pressure were putting a mechanical gauge on it tommorrow. But we both think its the sending unit because , at idle it shows 0 pressure and there is no noise or chatter coming from the valvetrain and if there was no oil going in there it would be very noisy.

Nixon1

...You advanced it 10 degrees OVER base? You sure that's a good idea?

cheese_kake

No OOPS I meant over what it was. It had been brought down 6* and we brought it up to base and then 4* over. A total of 10*, haha ya 10* over base would be alittle much.
