T-belt cover base timing marks

[DSMjrv]

is this how it is?

Heres some pics I took today. The crank is right on, and the cams are as good as can be. Mabye I have another problem causing my no vacuum...My car runs fine except that I have no vacuum and my brakes suck too.

Unless that is just a bad angle it looks to me that your cam is off by a tooth. Put a ruler up to it and take a picture.

thats what it looks like to me and thats why you wouldnt have any vacume or you have a hole in your vacume/boost gauge tubbing but u said ## car was running fine

If the notch in your harmonic dampener is not lined up with the T line while at TDC with all timing marks lined up, your dampener separated and rotated and needs replaced. I had the same thing happen. I couldn't figure out why I couldn't set my base timing, but that solved my problem.

? What about the marks down on the oil pump sprocket and the main crank sprocket to go along with the cam sprocket marks?

Looks like the autoadjuster isn't set right why the EXH cam is still rolled forward a bit.

These would definitely let you know if you got everything in time

I'll completely take the timing belt cover off tommorow and get some more pics up asap. Hopefully this is my vacuume problem and I can finally figure this damn car out!

So, my car would run pretty good if my exhaust cam is off a tooth, but low vacuum? Or is my intake cam off? Thank you guys.

I personally don't think your base timing is off at all. If you would rotate the crank slightly more the marks will line up. Have you done a boost leak test? Checked your Boost/Vac line to the gauge for cracks? Hell, the brake booster diaphram could be compromised or the hose split going to the intake manifold.

Having either the intake or the exhaust cam will change your vacuum slightly, but the car would still run "normally" as long as ignition timing was adjusted along with it. The powerband and spoolup would be different.

Check this out Timing Belt VFAQ. Scroll down to and read the paragraph in between #33 and #34. It looks like this may be what happen to you.

Alright guys, I have some more pics. I took the cover off and these pics are with the dowel pins on the cam gears down. Everything lines up pretty good to me...

 

[420a-t]

And here's some pics of when the dowel pins are straight up... is it ok if the oil sproket isnt lined up when the dowel pins are straight up, but it does when they are down? My oil pressure is fine via autometer gauge.

The oil pump sprocket posistion only matters on a motor with balance shafts.

From TDC all the timing marks should re-align after 6 revolutions of the crank. Your timing still looks good to me pending on if it has a balance shaft elimination. Otherwise, you should re-align the oil pump sprocket to its mark, while the crank and cams are set at their marks with the dowel pins straight up. TDC.

I have balancing shafts still. So everything is good then?

 

[Auto RS T]

No, all 3 must align then. Keep turning the engine over, If you can't get them all in time you should redo it.

They all line up if the dowel pins are down, not up. Does everything need to line up with the dowel pins up?

 

[snowborder714]

Yes, the dowel pins need to be at 12 o'clock when lining up all the marks.

When setting the oil pump, rotate the timing mark to 12 o'clock and release it. If it falls to the left (and the marks are pretty close to lining up), it's in phase. If it falls to the right, it's out of phase. If it's out, rotate it fully around and try again. Just keep trying until it falls in phase.
