IP timing after the valve job....
Just did my IP timing ,after valve job , 1 drop per second ..... but cam lobes are down ---- 180 degrees offffffffff ??? ..... at compression stroke fuel doesnt flow AT ALL.:banghead:
I test drove car today sluggish as hell , no acceleration , severe engine shake ... starts perfect ... , as for the valve adjustment just did them once after tighten headbolts , so will have to do it again seats are probably hammered in place,and just to be sure will check cam timing.... Am i right about 180 degrees off? Any tricks on removing oil filter prior IP removal?? Thanks. |

The cam lobes should be pointing up. You shouldn't need to remove the IP for a valve job.

I didnt remove IP , head is back on the car , i was rotating engine without head to check if oil that was in the cylynders didnt bend rods( had severe oil leak because of the broken exhaust valve), so chain got loose and skiped lots of teeth , so right now im just adjusting , so baby can run fine again.

I guess you'll need to remove the pump and retime it.

remove the front cover and take off the gear, and put the gear back on it when its back in time.

If the timing was 180* off, the engine would not run at all. Set the crankshaft at #1 TDC and recheck all your timing marks. |

Actually the engine would run, I set my daughters 240D 180 degrees off after losing timing after a head gasket replacement and as I remember it did run, but really crappy.

Actually it crawls , i walk faster then car drives .... about IP removal and re timing it ....do i have to lock IP ...to set the mark ... , when setting the mark on IP turn clockwise only?

If you've not yet removed the ip, I wouldn't. I thought I had similar issue with skipping teeth, but I called and asked some pros who rebuild these engines and they all said skipping ip teeth is very hard to do. If you have a FSM take a look at a cutaway drawing of the front of the engine that shows the ip gear. It's totally surrounded by a guide that would prevent most situations where you could skip teeth. Same goes for down below on the crank. So assuming crank and ip are still in sync, just remove cam gear and start over on the top and give it a shot. The 180 mathematically makes sense, since the crank has half the teeth, I believe, or at least it is somehow at a 2:1 ratio in some combination. At 180 off, I'm surprised valves aren't hitting pistons. Did you turn the motor over by hand before you hit it with the starter? If not, running rough may also be caused by bent valves. I'm by no means an expert on this job--only done it once, but I know I wasn't happy about the possibility of having to remove and reinstall the IP. Good luck!

Injection timing and valve timing are totally different concepts.

But my guess is that ip and crank are still in sync, so the only thing left is cam causing the timing issue.

Yes, my guess would be the cam was installed 180 degrees off not the IP. The valves would not interfere if they are 180 degrees off but the IP timing would be 180 degrees off as it would be injecting fuel during the exhaust stroke instead of during the intake stroke. You'd need to remove the chain, turn the cam sprocket 180 degrees and reinstall. Others will chime in if I am all wet here but since these are 4 stroke engines the crank will turn twice for each turn of the camshaft so yours is simply off by one turn of the crankshaft.

Unless the camshaft/chain were "randomly" installed, resetting the IP should solve the problem. The crank and camshaft are back in sync again at "180* off." It's just the injection timing that's off.

Since he didn't mention removal of the IP during this "event", it's probably not a wise idea to remove and reinstall the IP..........although the result would be functionally the same. Last edited by Brian Carlton; 08-26-2007 at 11:38 AM. |
