Rear cam tower cap leak

[matt1415]

Had the cam tower off about a year ago to do all the gaskets and just now I've ran into one of the same leaks I had before. Rear cap on the cam tower actually came loose this time and leaked down the side of the block. When I had the tower off I actually had the cap bolts torqued but it seems like nothing will please this cork gasket. Has anyone tried ditching the cork gasket for rtv before?

Best $16 bucks you'll ever spend:

It took me a surprisingly long time to find this particular leak on my '87 924s. &%$#@#$

grey permatex works well here.

You had me excited for a second until I saw the $36 USD shipping to Canada. I need to move to the states lol

I'll share a funny story and will try to keep it short. A few years back...just after I'd purchased my last 944 (an 85.5), I was pulled up to a stoplight when things started to get a bit smoky. Found oil dripping onto the rear header from what looked like one of the "classic" places - the infamous cork rear cam tower gasket. So I replace this but things kept leaking and smoking.

Long story short...I dropped the engine and eventually did a complete reseal. Good thing it did sort of need this - because in the process of taking things apart, I discovered several very loose cam tower bolts, located (you guessed it!) at the rear of the tower!

To think I could have simply torqued these up and called it a day! But on the bright side of things...I had fun sealing my engine and learned a thing or two in the process!

It's these sorts of things that keep me up at night.

With or without the gasket? If with, both sides?

i've slathered the gasket before and also just the permatex without any gasket. works fine either way.
