How do you remove the secondary timing chain
guide strips?
Any special kind of wire to retain the new foam
filters during reassembly?
Thanks!
OBTW: not a single scratch in the guide strips!

How many miles on the motor?
And why are you removing the guide strips?

[Mystic ZR-1]

Not many...
Read it here somewhere to remove
them prior to sending them out for PC
That oven is hot 400 degrees...

I didn't know there where guide strips in the cam covers.

Take off your oil fill cap and peek in the hole,
you can see part of one of them

[efnfast]

I've spent a lot of time rumaging around in various holes. Never looked in the oil fill hole.

This conversation is going south real fast...

Cam Cover Chain Guides clip onto a Chain Guide Holder held on by two small screws. Cam Cover Chain Guides

I switched from Scotch Brite to Marc Haibeck's new Cam Cover Vent filter material Cam Cover Filters

I think any kind of wire the size of a regular paper clip would work fine (bend straight a paper clip and cut so about 3/8 inch of the Paper Clip sticks out each side of the Cam Cover Filter Housing). Insert the straightened Paper Clip after the Cam Cover Filters are installed. Then.....bend each end of the wire sticking out of the Cam Cover Filter aluminum sides about 3/8 inch 90 deg so they will not drift out of place.



Be sure you do NOT loose those two dowel Pins aligning the Cam Covers with the Heads (one each end of the Head)

Thanks!
A few more questions...
The guide strips "pop" off and the chain guide holder has
screws that can't be seen with the strips in place?
What's the best way to "pop" them off?
I just want to be sure before I screw anything up...
Got the new foam from Jerry.
Should I use A136 on the end plugs when reassembling?
A136 on all machined mating surfaces or just around the
edges and plug recesses? (not on o-rings of course...)
Thanks again for the advice!!!!

What's the best way to "pop" them off? Lift up on each end or get a small screw driver tip and push out on tabs on each end under guide.
I just want to be sure before I screw anything up... I do that some times experimenting

I use A136 on the end plugs when reassembling? you do not have to put anything on the two guide pins.....but YES on the two rubber end plugs each end (applying the A136 on the grooves in the Head and Cam Covers and NOT on the rubber End Plugs themselves)
A136 on all machined mating surfaces or just around the edges and plug recesses? (not on o-rings of course...)
Exactly except I do not apply A136 in the plug recesses where the "O" rings are placed but DID apply A136 around mating surface just outside of each "O" ring.
Thanks again for the advice!!!!

Apply A136 on the Heads (I actually apply A136 to the Head and not the Cam Cover after DEGREASING the surfaces) and in the grooves of the cam cover rubber end caps on both the Head AND Cam Covers

Make sure you clean the grooves and rubber caps completely before applying A136.....and...NOT TOO MUCH A136.....just use finger and smooth out flat on surfaces of Head. And make sure you have the 4 "O" rings in place set in each recess of the Head (one each spark plug hole).

AGAIN.......apply a small bead of A136 in center of mating surfaces on the Head and then smooth that bead out ALMOST to the edges of those surfaces with your finger (very thin surface of A136 ALMOST to the edges of the mating surfaces). You do not want a lot of A136 squeezed out and into the Head area during assembly of the Cam Covers onto the Heads.

When you get the Cam Covers installed, take a paper towel and wipe clean ANY excess A136 that might have squeezed out on each end of the Cam Covers around the rubber end caps and all around each Cam Cover. There should be not much at all squeezed out if you did not overdo the use of A136.

I do NOT apply A136 beyond the bolt hole on each side of each journal making sure I do not end up with A136 messing with the Cam Shafts. In other words....stay away from the Camshafts journals at least 1/4 inch more or less (I keep A136 just outside of the bolt hole edge) each side of each Journal.



I think I actually did everything above on the Cam Covers and NOT the Heads one time but definitely do not apply A136 on BOTH. Either the Heads OR Cam Covers but not on BOTH. Except where the Rubber End Caps are involved (apply A136 in BOTH Heads and Cam Cover Grooves that take the Rubber End Caps).
