I recently finished a cylinder head job on my 2000 Taurus 3.0L OHV
, and when I start the car now, I hear a very pronounced popping noise, like a backfire, or something along those lines. I have three ideas of what could be the problem.
1) I noticed after I put the EGR
valve onto the intake manifold that there was supposed to be a gasket between the mating surfaces.
2) I also noticed when working on cranking down the rocker arms, that one of the rocker arms would not tighten down (and yes, I did make sure to rotate the engine to TDC
of the compression stroke for the cylinder whose rocker arms are being tightened.). I also follow the firing order when tightening the rocker arms, but one of them, the one closest to the drive belt on cylinder #2, would not tighten down. The hold down bolt itself would tighten down, but the rocker arm was still loose. Could this be a valve train problem? If so, would I have to take the cylinder head off to fix it?
3) Lastly, I thought I had to take out the synchronizer (AKA distributor) in order to replace the camshaft position sensor, which it turned out I didn't have to do. Long story short, I put the synchronizer back in, but at a wrong angle (the repair guide says to install it at 38 degrees counterclockwise from the engine center line). From what I have read, this generally causes a chirping noise when worn, but I have yet to hear of anyone doing anything like this. Also, the installation procedures in the repair guide only outlines how to install it if someone marks where the synrchronizer previously was, which I did not do. From what I have read, I assume that I should turn the engine to TDC
on piston #1, and then install the synchronizer at 38 degrees from the engine center line.
Any help on this would be much appreciated.
