Default Help! Timing Chain Cover

What am I doing wrong, what do I need to know? I am replacing the timing chain and oil pump on the donor engine before I install it in the car. I can't for the life of me get the timing chain cover back on. Do I really need the tool that the factory manual calls for, or is there a trick that I need to know? For the specifics, it's an 01 DOHC. I thought I had it earlier, I don't want to force it on. Thanks for any help.

Pretty sure it's just tight from the alignment dowels and the oil pan lip it needs to slide into. The safe way is to drop the oil pan, that'll involve removing the engine-trans brace too.

The somewhat risky way is to make sure it's on the alignment tabs properly and wack it a few times with a rubber mallet along the oil pan, may help to tilt it into the oil pan groove first then swing it to the alignment tdowels (or just pound the dowels flush with the flange and then it goes on no problem).

I'm going to disagree! Negating the function of the dowels is a big invite for crank seal or oil pump problems. I would never do that!

The cover should slip on without any hammering, even if the pan is left tight. I do agree that it is probably a bit easier if you tilt the cover so the pan area goes in first. I assume all the RTV sealant at that pan joint has been cleaned off and the cover is going on with fresh (slippery) RTV there.

PS: Did I read correctly, the engine is out of the car? With the engine out that timing cover job should be rather trivial. It is when it is in the car that it can be a real chore because of limited space to see or work in. Also, I can't think of any need for "special tools" to install that cover. Can you describe what you are referring to about the tool?

If you have the OLD crank sprocket then stick it through the cover onto the crank and rotate slowly to line up with and engage the key way, now it all slides into place IF you have cleaned out the dowel holes and cleaned off the dowels.

I'm with OldNuc on this one. The old gear is key. That was the first thing I thought of when you mentioned your difficulty.

Thanks for the replies, after stepping away from my frustration, I took the old crank gear and put it through the front side, like I had when trying to get the cover installed, it fit just fine, then I tried putting it through the inner side and the oil pump actually have to slide a bit before it would fit. Now it slides right over the crank. So, now I have to clean off the new silicone and do it again.
