Front Crankshaft Oil Seal DIY

You don't say? I've never noticed that

Sarcasm?

Nope, no sarcasm. I never knew that pinhole was there. I thought the only way to lock the flywheel was to bolt one of those backets from the flywheel bolt to the bellhousing bolt.

Oh, yeah its pretty cool. I didn't know it either until I rebuilt my vanos and changed my HG.

Hmmm I guess that means to use that feature, there's a certain orientation the flywheel has to be bolted on by? I've never paid attention to that. :/

Well, I'll be changing the flywheel this weekend, so I'll get a second chance

Yep, look for the hole in the bellhousing and bolt it lined up with the hole with the motor at TDC. You don't have to take off the valve cover to see, just use a mirror and look at the timing marks on the crank

Cool. Easy enough.

please essplainz, as i are confuzzeded...

there is no explanation as to why the hub was replaced in the thread...i checked...

i don't think it's required, but like u said it's on occasion. my mechanic suggested it's a good idea to replace the hub while we have access to it (preventive maintenance).

good thing he has 450 ft lb air gun for the crankshaft bolt.

So I take the belts off then take off the pulley , do I need a harmonizer too?

but no, you should not need to replace 'hard parts' like that unless physically damaged.
