5efe cam timing


Of course its the little things that are a PITA down the road.


Spun a rod bearing, took the motor apart, etc etc.

Forgot to mark the timing belt with where the cam timing gear and crank timing gear were to preserve the timing.

I'm 99% sure that the cams are properly in-sync.

I'm pretty sure I eff'd up with the cam/crankshaft timing when I put the timing belt back on. Got the motor to run for a few seconds, ran like shit, stalled and won't start again. Confirmed I have spark and fuel. Did some research and it looks like from what I found that I need to set the crank to TDC on cylinder #1 and then align on the cam pully with some timing mark on the bearing cap.

If anyone has any input or advice, I'm all ears. Will probably be trouble-shooting and fixing this after work tomorrow.

Forgot to mention...I have a 92 Paseo 5efe in my Terc. 3ee diagrams don't do a whole lot for me.

The process is the same, just in your mind replace the 3e/2e in the above pic with 5e/4e, respectively.

Also, with respect to the cam phasing, there are like 3 dots on I think the intake cam gear, and like only one set of dual dots on the exhaust gear. It was not very clear which set to align, so I basically looked at a known good engine to set the cam timing. If you need confirmation on this I can help.

Also when aligning the cams on the intake cam at TDC cylinders 3 & 4 are pointed down beside the lifters. The exhaust cam has cylinder 1 pointing at the radiator.

I need to get the car back up and running ASAP and wouldn't have access to a known good motor until this weekend at the earliest. If you guys have pictures you could post up of what the cam pulley/gear should look like with the #1 cylinder at TDC that would be awesome to confirm that its correct.

I suspect & hope that its off by one tooth on the cam gear, which would explain why I was able to get the motor to run...though it ran like shit.

Will post up in a little while after I go outside and mess with it.

Thanks for all the help thus far.

I'm 99% sure my cam phasing is correct. On the inside of the cam gears there is a yellow mark that looks to be from a paint pen that when meshed at that part of the cam gears makes a solid line. I got lucky on that one.

I eff'd up by rushing and not taking my time to mark everything the way I know I should before disassembly. I was tired, it was getting dark and I needed to get the motor apart.

I guess I need to go outside in the rain and cold and pull the upper timing cover & valve cover and check to see if the cam timing is wrong(which it probably is).

If I remember correctly, thats exactly how the cams were when I installed them.

Here is all I have on hand right now showing the cam phasing, check the video in this thread. What I recall is the #1 exhaust cam points forward to the front of the engine, and the #1 intake cam is pointing about halfway between forward to the front of the engine, and 180* from contacting the lifter.

It lives!

Runs better than ever actually.

As I suspected, cam phasing was not the issue.

Turns out I overlooked torquing the cam gear bolt to spec and the timing belt was spinning the gear but not the cam. Simple fix, just time consuming.

I still need to get the ignition timing and idle set just right, but it runs.

I also have a short list of non-related things that will also be taken care of this weekend.

Thanks for all the help guys.

There should be a pin that engages the cam gear to the cam to align the 2. If the cam gear was spinning but the cam was not, you might need to look for where this pin went. Plus not sure how you would phase the crank and cam without this pin making sure the cam gear was in the right place so you could look thru the hole in the cam gear to the dot on the #1 cam bearing cap.

The pin never went anywhere, I forgot to tighten the cam gear bolt so the gear was just spinning but not engaged on the pin. No harm done, engine runs great.

About to go outside and set my ignition timing, and idle.

I see two timing marks on the bearing cap. Which one should i align the 5e hole on my cam gear to? The front dot or the rear dot?

From what i get out of the fsm its the one at the rad side of the bearing cap. That's how i got mine timed and it runs fine.

if you're running a 5E motor, you use 5E timing marks
