Time to do HG & Timing

[Threehz]

How long does it take to do HG, timing components, and related head work? I know it will vary a lot from person to person and car to car, but any general estimates would be helpful.

Thanks

Assuming you are familiar with how the engine is put together and how to remove/install the crank damper bolt, you should be able to knock it all out in a weekend.

In addition to knowing how to do the crank bolt be sure to hit the exhaust manifold nuts/studs with PB blaster in advance as that's the next largest PITA.

Budget 4 hours for removal if it's your first time and less for reinstallation. Getting the head machined/checked? Also be sure to get new head alignment dowels/rollpins.

dude straight up it would probably take you no more than four days if you have all the gaskets and stuff. and thats a lot of time. I did my head gasket last week its super chill and straight forward. dont even be scared of the m42. everything is common sense trust me. Besides the timing which isnt scary ether. Just take your time and dont snap a bolt in your head.

Took me a total of 6 hours to replace mine the first time.

ive done so many HGs in m42 I can do one in like 3 hours. lol

yea i can do the head gasket in 3-4 hours. lol. definitely had the head offf more times than i wouldve liked.

first time doing all of that will probably take you a day of on and off working.

Why new roll pins? I am assuming that they would be misshapen or something similar?

Yeah, there is a fair chance they will get messed up, and of course they cannot reasonable be put back in to round.

It's more important when you are getting the head machined as they need to be removed if they stayed in the head.

Interesting. My machinist removed them before he milled the head / block. I will ask if he simply reused or inserted new ones.

If he reused them do ask if there was some special trick, as I was unable to remove any while keeping them in round.

'toaster ... he removed and inserted new ones.
