Cam cap loctite Help?
I've finally restarted the re assembly of my '85 but have one issue that Search didn't help me with. What type of Loctite do I need to use on the end cap for the cams? I'm not refering to the black round puck seals but the caps/bearings that are at the front and the back of the cams. The intake and exhaust caps are one pice and remember someone telling me that, since they are passed the valve cover gasket, they need to have a sealant applied during re assembly of the cams. otherwise oil will seap out and drip onto the exhaust manifold ( I had this problem ever since I first put the engine together back on '02).

You should absolutely not trust anything I say regarding engine assembly (having never assembled one....), but when I disassembled the GT motor and the GTS motor, both had the same loctite 574-looking stuff under the cam caps as they did between the block and the girdle. Both gave the same whiff of anaerobic sealer when I lifted the caps off the surface of the head.
Decent loctite 574 discussion if you haven't seen it:

Is there a Permatex or ther equivalent of the Loctite 574? No one in Ontraio seems to have it in stock and don't really feel like waiting for a week and a half for them to order one in from the US.
Rest in Peace

That being said, Volvo and MB both have a sealant that might work.

Years ago when I was a teenager back in Europe, I've used Hermetik to seal up motorcycle engine cases and the Loctite 574 seems like a simmilar product to it. If I could smell it, I woud be able to tell it they are the same or not. Hermetik has a very uniqie smell that sticks with you forever.

Just ask for the stuff for the cam covers for a 850
There are a couple of others this one is made by Elring "Curil K2, I seem to remember getting it from Volvo or MB once instead of the branded stuff, I did not use it as I want to use the right product, they said it is the same, but it smells different and is yellow in color.
I did not have any of the MB stuff, so I do not have any numbers for it.
Remember, clean and quick when you are going back with it.
I would still wait and get the 574 if it were my motor though.
Good luck

518 looks quite similar to 574. Both are anaerobic sealers that cure at about the same rate.

Imre....I've got exactly the leak you're trying to prevent. Is it possible to remove the front caps without removing the cam gears? When I dove into this the first time, I got the cam cover off, but stopped when it looked like I would need to remove the cam belt, the gear and rear timing belt cover/plate to gain access to all the bolts necessary to pull that cap off.

I hope this helps.
