Subject: Exhaust cylinder studs & threadlock
Content-Type: text/plain; charset=iso-8859-1
Hi all,
Back to the exhaust system and crossover front and
rear pipe attachment to the cylinder heads. Details
below.
My original question: what can one use to help lock
(threadlock) the studs on the cylinder heads (see:
http://www.esu.edu/~gstylia/vw/cyl4stud.JPG),
or even the crankcase (for future reference. Regular
threadlock failed!
By the way, I started with studs but they wouldn't sit
still. I placed medium strength threadlock paste, let
them settle for 24 hrs, but as soon as the locknuts
engaged, the studs went in. It was a nice setup, and
very easy to set the pipes on the cylinder heads. To
make the short story shorter, I ended up doing what
Frank suggested ... 30mm bolts. I struggled, almost
damaged/stripped the threads of one of the cylinders,
but made it. I ended up saving and using the old and
original exhaust pipes (somehow, the new ones wouldn't
fit ... go figure), but next time I will have to
replace the whole thing.
Oh yeah, I ended up getting the Nickel 2400F based
anti-seize (per TC) for the bolts and other
connections. It made it harder (kind of slippery
feeling) to position the bolts and everything, but
what the heck.
I too love to see a clean engine! Some people don't
believe it when they see my engine(s). The first time
(8 years ago) I cleaned the engine was with WD40. It
did pretty good, but then I thought that if that thing
gets into cracks and openings, it may do some damage.
Then, I used different types of engine cleaners and
detailers. The best detailer I used was from a company
that I don't remember its name. It did a great job. My
next step may be a toothbrush ... I am just thinking a
little fluoride wouldn't be bad. Maybe the whitening
one. Ha! You never know. I may try it. I'll let you
know if I do.
Thanks,
geo
