TIMING CHAIN NIGHTMARE

[JAX01X5]

Hi guys. I am new to the BMW seen and boy have I picked a doosey . I got a good deal on my 01 x5 4.4 knowing it had a timing issue that the previous owner did not want to pay to have repaired. I researched m62 timing issues and was fully aware of what I was getting my self into but after opening it up today I find that it was far worse than I had imagined. The shutter plate was loose spinning freely, the center guide was broken with absolutely no liner, the right guide was completely destroyed with the only 2" of it left. 3 out of the four cams are of at least 10 deg and this is just the beginning of what I have found. Does any one know how much clearance the valves have before they hit the piston? I have decided I am willing to tackle the challenge and willing to take any advise you guys have to offer. I am posting some pics so you all can see what I am up against. I just don't understand Why people continue to drive there cars knowing they have a major component failure.

Valves might have been tagged already. Did you do a compression test? Maybe better to replace the engine. Do a compression test and if any of the readings are low, maybe better to cut your losses and part it out.

Only kind of a good deal for a car like that is if he gave you the car for free.

I did a compression test and cyl #4 was low but the cam position is so far off that it would hard to say whether it is the valve or the cam position. I found another motor with 150k for $600 but what's to say the guides are good on that motor. I have the parts for the repair I think I'll take a gamble and hope for the best.

cant be worse than the ones in this engine. I'd almost go ahead and buy that engine to be honest. at the least, you could frankenstein one good engine from the two and then sell the extra parts on ebay or craigslist.

get that engine over and open it up, if it looks good, close it back up and toss it in and then part out the original one. then flip the car.

If you know the cam timing is out, don't turn the motor over.

About time those heads came off for a proper inspection. Anything less than that is a shortcut.

Yeh.. I here that. Funds are getting low. Spent $700 so far not including the cam locks and vanos timing tools.

You do know that you can rent those right?

I called "GAS" and they put me on a waiting list. Could be two to four weeks maybe longer. I'm thinking I'll buy one and try to sell it later. The SnapOn guy comes by the shop every week maybe he could sell it for me. Do you know anywhere else that rents them?

[Joshdub]

That is quiet the wait. You might try these guys as well.

I tried them as well but they get there's directly from "GAS".
