I have my 350 out for a timing gear change and detail of the engine compartment and motor.

Questions.....

This is the first time I've torn into a Olds motor, I believe its on TDC the #1 piston (drivers side front) is on the up stroke & the rotor is pointing to it. But the timing mark on the cam gear is in the 12'Oclock position is this right?

Any tricks to sealing up the new oil pan front/rear main seals, timing chain cover & water pump gaskets for a leak free fire-up?

I have thread sealer & Med (blue) Loctite should these be used in the reassembly?

Thanks Guys!

 

How many miles on it, I have to do my timing chain someday as a precautionary measure. I'm at 82,0000.

 

Yes, this is correct. You can also install it with the dots lined up at 6 and 12 o'clock, which is TDC on the exhaust stroke, then install the distributor later. I recommend this method, it is pretty easy to damage the dist if it is installed when dropping in the engine. Also, aftermarket chains can be off, if you can, it would be good to degree the cam.

As to the pan, use the brush on aviation type sealant on the long sections and RTV Black on the 4 corners where the end seals hit the cork. Take your time tightening the pan down and do not over torque.

 

It has 144k.

CaptJim I never pulled the distributor the motor came out with it in.

Should I run Loc-tite?

 

OK, you just have to be careful dropping the engine back in. Yes, Loc-Tite on both the crank and cam bolt and torque to spec.

 

Other fasteners, no loctite
no sealer needed on water pump bolts though the lower center 1/4" bolts can be sealed with say form-a-gasket #2.

If you have the engine OUT, as it appears, it would be a good idea to replace the freeze plugs before they rust thru. Super easy right now. Form-a-gasket #2 is good for those also.

 

Nice timing on the timing set, looks like it was just getting ready to drop all its plastic bits. Nice work on the painting also.

 

Good idea, just be careful installing them. Clean the block VERY well with Emory cloth or similar. Put some sealant on the plug and allow it to get tacky, then use the proper tool to press them in. Also, when doing the rear, one plug is the oil galley plug, not a freeze plug.

 

Uh oh. I recently did my timing set and never used loctite on the cam bolt. How worried should I be?

 

How many miles were on that timing set?

 

I wouldn't worry about it as long as you torqued it properly. I have never used loctite on that bolt; just torqued it to spec. 4 camshaft changes in the past 33 years with no issues.

 

Awesome, thanks!
