DIY: Setting Cam Timing on M96

[theiceman]

great thread and very informative.. but green loctite ?? that stuff is usually used as bearing retainer on stuff that is designed never to be removed.

are we sure about this ,? green is even stronger than red which requires heat to take out does it not ?

I realize this is an old thread, but want to ask: has anyone done this successfully with the engine IN the car?
I've replaced the engine twice already (first replacement had intermix) and dread another round. I'd also like to drive the darn thing this summer!

It can be done, but it is the worst "ship in a bottle" project you have ever seen. Quicker and more accurate if you drop the engine.

Suspected as much, looking at the Bank 1 oil pump.
Thank you.

If it is difficult for JFP, for an amateur it is ......
If you read between the (many) lines in post 18 above you'll visualize a few of the problems.
In anticipation of the next (inevitable) time I must do such a job I used my 'ship-in-bottle' experience to justify the purchase of all the extra tools and equipment necessary to make engine/gearbox removal as fast,safe and easy as possible.
A hydraulic cart is an example of the equipment I indulged in.

I have a cart, and a lift. It gets tiring after the third engine remove and replace.

I used this procedure to retime my 2000 2.7 engine after changing the chain tenser pads. When I reinstalled the cams I eye-balled the timing thinking that it was close enough. When the assembling was finished I found that the sprocket was not properly placed and I couldn't turn it enough. I found that it is possible to reposition the sprocket in the chain without taking it all apart again. Before starting I put a mark the sprocket and a mark on the chain that I wanted the sprocket to be aligned to. Make sure you are going to adjust it in the right direction!
1) Remove the chain adjuster (that's the name in the PET, it is often called the tensioner)
2) Remove the 4 bolts, pull the sprocket off the end of the cam and drop it towards the crankshaft to get enough slack on the chain
3) turn the sprocket to align your marks before replacing it in the chain and reinstalling it on the camshaft.
4) reinstall the 4 bolts and the chain adjuster

Here it is after the adjustment. I think my original problem was that the chain aduster was not installed when I eye-balled it during the assembly and installing the adjuster moveed the cams.

Incorrect.
Green Loctite 290 is a 'wicking" grade of medium strength thread locker.

That is great additional info thank you.. (technically i was NOT incorrect but thank you for that curt response. i was confusing it with green loctite 638) I will proceed with my blue as it is all I have and in sure it will work fine as it is medium strength

The original article did NOT indicate which version of green loctite .

For those in the future please be aware ..

There is a green loctite 290 as posted below
There is also a green loctite 638 which is NOT to be used as this is bearing retainer and very very strong.

cheers all .

Continue to use this excellent thread as a resource and have completed the task .. however .. have any of you noticed anything like this before ? .. as you can see , this will be somewhat difficult to set up lol..



fortunately i was able to get the alignment tool in on this side of the engine and it popped in fine.. but is a little unnerving .

Think hans had to many pints at lunch when machining some bits.
