I've just noticed I have a slight leak comming from what looks to be a head bolt (not freeze plug!) I tried to tighten it up, but it's tight Any ideas??
On the up side I just had my 700R4 installed. WOW, what a difference! I love it! Used to be turning 3600 RPM's at 70 MPH, now it's right at 2100. Now if someone just tells me what's up with this leak, I'll be a happy camper.
Thanks for your input.

Any ideas??

The bolt is tight and you have this leak.

My $0.05 on it = bad head gasket.

The infamous leaky head bolt into the water jacket trick.
Drain radiator until water level is well below the Head bolt that is leaking. Remove the bolt and put on some aviation type gasket sealer on the threads and torque it down. Refill the Radiator and see if leaks. Hopefully it's not a head gasket problem. Congrats on your gas saving from your tranny swap!

RJ, I'll give you your nickle back I don't want to hear that kind of talk It's on the driver side, middle of the block, just below the header flange. I can see the fluid just below the head of the bolt, nothing leaking anywhere else. I re-torqed all the intake manifold bolts, and everything is tight

I had a leak out the driver side tailpipe of my Wagon when I first got it and thought, "Oh man the head is warped."

But I checked all the head bolts and most were loose. After I re-torqued them the leak went away.

At the price of premium (or better) you should recoup the money laid out for the tranny in no time. To us financial wizards that's known as your ROI (return on investment).

Bluemeney, now that's the kind of answer I'm looking for! THANKS!, That sounds like a job I wouldn't mind doing
I had a couple of my intake bolts leak oil a few months back, and pulled the bolts, put some sealer on the threads and that took care of it! I was hoping someone would chime in with an easy fix. Thanks again!

Tommy, nope don't mind you asking. I traded a buddy a vette engine and 350 tranny I had for it. It's an early 700R4. I believe my rear end has 377 ratio.

I use spray Copper-Coat gasket sealer on the bolt threads when I build an engine for this reason, worked pretty good so far.

Had the same problem but under the valve cover into the oil. I used Permatex high temp thread sealant #59235 sealed it and on more problems.
