Timing Chain Inspection and Replacement

[Tynan918]

Is the fan, water pump, and harmonic balancer the only things I remove to get to the timing chain cover ?

One of the reasons I suggested cleaning the entire front of that motor. Lots of 'wet' coverage there. Things need to be cleaned up as much as possible to help ID trouble spots.

Look at the thread I just posted. It started out as a "little leak". LOL

The passenger side bottom timing cover mounting bolt hole has a broken stud in it...been fighting with trying to get a new bolt in it since the day before yesterday, and after just checking it, there is a broken stud in the hole keeping me from installing the new bolt...

Is it a big deal ?

Should I extract it or extra tighten the remaining bolts installed ?

With the dowel pin holes on the timing cover, can I drill one of those slightly bigger to more easily slide over one of these dowel pins ?

With the oil pan/timing cover gasket in place correctly, I'm able to line everything up but doesn't seat down all the way to the engine block because of one side dowel pin...

I've tried pushing it in but the timing cover hole seems to be a bit smaller than the dowel pin, keeping the timing cover from seating all the way down...

I can place the first and only the first dowel pin in correctly from either side, but the second attempt at the second dowel pin, it doesn't slide in, allowing the timing cover to seat in correctly.

it kinda is a big deal,if there was a bolt where that dowel's residing above it maybe it'd keep it but seeing it's the last bolt @the bottom it's a gamble.

If extraction is a must, what tools will I need to extract it ?

I have an 18v cordless drill...what else is needed ?

My thought exactly...

Thinking maybe it was the cause of my leak actually, or part of it...

You can try these. Be sure to center punch the bolt and use a reverse thread drill bit. Kind of stinks that the gasket is in place, because you’re probably going to damage it. Be sure to cover up the oil pan so no metal chips get in there.

Center punch ?

...And ok on the drill bit.
