Opinions vary, I typically don't use it there

 

[Jim]

I do...

Hi Jim, Ever have any negative issues with it on the base gasket? Do you coat both sides?

 

[Jim]

I use Permatex Aviation gasket sealer. It's all I've used in about 50 yrs of building/repairing engines... if that answers your question.

Both sides.

Both sides.

It's all I ever used on my air cooled VW's. I can still smell it.

What Torque spec do you all use on these Cam Chain Guide M6 bolts? I've been using 7 ft-lbs recently on all M6 during this build. But Stopped at 5 ft-lbs on these... Did not feel like they were getting any tighter.

Base gasket was installed upside down. The stock material must have been upside down when they (the supplier) cut it. (No Yammabond.)

New Cam covers worked out perfectly, centering the cam / bearings, line to line across the assembly. (Without gaskets/O-ring for centering.)

Calling it a day - Got the head assembly together. I am happy with the way the Cam Covers turned out.

I use about 6 - 7 ft lbs.

Thanks Jim. I'll see if I can't sneak it up to at least 6. Any idea for torque spec on the oil pipe / line ? (With the copper crush washers.)

 

[Jim]

I think I'd be tempted to just let it be at 5 ft lbs. Don't recall on the oil tube... 30 ft lbs rings a bell but you best just look it up... not sure if thats right or not.

I've never got on with base gaskets I was leaving them out and sealing with wellseal but because I had some clearance issues have had gaskets unlimited make me some copper ones just have to ask them for the size you want, I had 85.5 made for 750cc

 

[rehar]

Thanks for all the inputs. That copper base gasket looks great. Got a few more things done today. Need to adjust the valves and install the VAP 277° Ignition. Maybe next weekend. It's amazing how few torque specs I can find - the four different manuals I have + Internet...

Click, click... There is a noticeable clicking noise from the head, just after each valve starts to close. Is this normal? I can't imagine what would make this noise?

Engine is buttoned up, valves adjusted to spec (I believe). Assembly lube all over the cam, lifters, etc; otherwise no oil in the engine yet.

 

[Jim]

It could be from the chain. After the cam lobe passes thru max opening, it's gonna go from loading one side of the chain to loading the other. Have you adjusted the tensioner yet?

 

[rehar]

Hi Jim, I noticed the noice with everything tightened and adjusted. Then I removed it and still - same clicking noise. It is also consistently, noticeably louder on the right, intake side. But makes noise just as each valve starts to close. Hmmm...

 

[Jim]

Any chance of a video?

 

[rehar]

Will try tomorrow night...

 

[jay760]

Probably the cam chain adjuster, they click sometimes if the brass washer is missing

Videos have to be hosted off site. I load videos to my Youtube account then link to them here.

Thanks Jim. I have never put any content in to Youtube, up till now.
Here is the video link. Turning engine over via sprocket bolt and a ratchet, transmission in 5th gear. Sparkplugs and chain tensioner removed. Sorry about the quality of the video, hard to spin the engine, while squatting and trying to record a video. I guess I'm not very coordinated. Anyway, I caught 3 clicks of the 4.
