Are these timing chain marks off?
 

View image: image1


They're not perfectly 12 o'clock and 6 o'clock, does that mean they're off or is that normal to not be precisely up and down? I'm worried about trying to take this off if they're not aligned.

And is it really all right to use an impact gun on that cam bolt?

It's probably from the chain being super stretched out. When you replace it that should be more directly in line.

So yes, they are off.

They appear off to me too

Yeah, when I turned the crankshaft to face exactly 12 o'clock, the camshaft was exactly one tooth off… So I guess it had jumped a tooth. Plus there's a lot of slack in the chain. Boy, I'm glad that I took the advice of you guys on this forum and went ahead and bought a timing chain kit while I was in here doing all this other stuff. I hadn't originally planned on changing the timing chain.

How do you fix the offset timing marks?

I can't find anything detailed on that. Is it all right to just rotate the crank and cam, using their respective bolts, until they line up perfectly, then attach my timing chain? I read something about removing your spark plugs first, is that necessary? I'm about to replace them anyway, as well as wires, but I was going to wait a week or two till I had time to change out my valve cover gaskets and get that upper intake manifold off for better access.

Removing the spark plugs is so that you won't have any compression so the shafts are easier to turn to exactly where you want them. You don't have to remove them though.

Is there a video or write-up on timing chain replacement and how to correct the situation that the OP is having? I've never done this repair/replacement and always like to be armed with as much knowledge possible.
ZA105, what is the original repair you are aiming for? Oil pump gears?

On our rovers it's easy.

The gears simply slide on.

Take the gears and chain off together, turn one of the shafts one tooths distance the correct direction and you should be on the money.

Rotate the assembly and double check, realign.

Just like that? No fuss, no muss?

Thanks for the replies, guys. Looking forward to getting my car off the jacks and back on the road. But first, waiting for a new front cover dowel pin to come in from Atlantic British... And a freaking #3 pozidriv bit from Amazom to get those darned screws off the oil pump.

Chubbs878, here's the write-up I followed for the timing chain: https://landroverforums.com/forum/di...rite-up-77138/

My list of repairs for this particular job include:
Water pump gasket, front cover gasket, oil pump, front crankshaft seal, timing chain and gears, oil pan gasket.

Next up:
Valve cover gaskets, spark plugs and wires, brake bleed, transmission, transfer case, axle and differential fluids, and a broken front passenger window regulator repair, piece bought off here from a user.

Funny, my wife and I bought our 2004 SE Disco about the same time you bought yours, chubbs878, and we looked at a 2003 SE7 with about that many miles too. It was silver I believe, being sold in Fayetteville, AR, where we live.
