See that half moon hoops for the line bore machine? Right at those 8 corners do dab a tab of sealer at those areas. Look in the book for those glue hits.
The roundish thickened part of the case wall where the 7 bolt threads and that 1 positioning pin were set. Only explanation I found about sensor cover installlation is a table with torque spec for the sensor cover bolts and a note about nonpermanent locking agent (1). They do not even say anything about the sealant but I see it was applied when assembled at the factory.
As far as a bond back on that bolt? Pass on my end. You call that ball on your end. I use very little if none after an engine build. I do not want some internal contamination that does not need to be addressed if it is not leaking. Make sense?
I think I will do a drop of blue thread lock on there if the outside temp gets up to 60 F. No reason to use that stuff in the cold. If it does not firm up quick as you can get the bolt in, it will not fill any gaps in the threads at all.
*Did you stab the tensioner as per book to preload it out of the cartridge? How do you know the piston came out for sure?
Yes. Last time I re-re-reinstalled it (so I could turn the crank w/o skipping time on the inlet sprocket) I heard and felt the pushrod ratchet out. This last time, I was not as quick on the pull back of the screw driver so the ratchet feel was not very pronounced. I felt something though. I also turned the crankshaft and watched the Cam Chain on the teeth of the Inlet Sprocket. The chain maintained good tension and no lifting up as though it were going to jump a tooth (although the chain does not ride quite as tight on the Inlet sprocket as it does on the Exhaust--just cuz we are pulling on the Exhaust with the chain and pushing up at the Inlet).
I then rolled the the tensioner screws back evenly until I saw the tension body come along with the bolts. I stopped so as not to trigger another lock tumbler.
That worked really well for me the last time. NOw that I am familiar with how this works, I am a lot more confident about if the tensioner pushrod pops out or not. The spring was sprung, I'm sure. Otherwise I would have seen the timing chain start to lift w/o tension on it. Although the loose bolt test a 100x safer than observing the cam chain tension, there is the slightest chance that pushrod might be right at the edge of ratcheting to the next stop. You losen up a half thread and that could be all it takes to jump to the next setting which would be 1 setting too tight (although, if it is already that close, might actually be an improvement, hey?).
But, do you see how that dot to cam comes around again in so many revolutions?
Yeah. It's a beautiful thing. Now that you mention it, I should start playinging with the animation software I got with my Adobe Suite. Ps might not be quite enough for complete engine internals. IDK. Would be cool but no time, unfortunately.
That engine goes together one way and if you hit the factory marks? Shedingdongdisdone!
Getting closer. I torqued the head cover bolts according to sequence. I used 70 in lbs instead of the spec 87. felt good enough. I think that might be all it takes to solve the leaky gasket.
