i got my 28 started on the 19th at last only to find i had a slight leak with the head gasket that would cause water to blow out of radiator every 4 or 5 minutes. block has been sleaved back to standard and mag'ed as has the head (no cracks), block was decked and head surfaced. i am using one of the olson gasket head gaskets that they have reproduced, which is a little different then a nos gasket. the head was torqued in stages ot 63 foot pounds and then 2 more times after engine was hot and cooled. any ideas!

solved the problem? it can not seal. I have a motor?

Dell,
I can share your pain.
A few years ago I had an even worse problem with the head gasket on a 1929 633. I had done everything you have done, decked head and block rebuilt engine etc and yet when I filled it with water in preparation for first start up, water leaked out the edge of the head gasket.
I immediately thought I had failed to tension the head down but after checking and re-tensioning it continued to leak. At this point I had not attempted to start the engine, the gasket was leaking in a number of places just under the static head of water from the radiator.
It was a new gasket manufactured locally (Australia). After much head scratching I ordered a new gasket from Olsen and removed the head to examine the leaking one. I could not see anything wrong with it and I showed it to a few others who said the same. While waiting for the new gasket to arrive I fitted the old gasket that came out before the rebuild and tightened the head down just to see if it was a problem with the head or block. It sealed so I proceeded to get the motor running. There was no evidence of a problem with the motor running on the old gasket . That old gasket has now been in about 3 years and we have driven the car a few thousand miles. The new Olsen gasket is under the seat just in case but it looks like it will not be needed. It makes me wonder why we spend the money on a new gasket every time we remove the head.
I would try your old gasket, if it does not leak then it has to be a problem with the new gasket.
I am sure we will be very interested in what you find.

Factory recommended a sealant to the gasket. I pref. the Alum Copper gasket and i spray with Alum Paint for the sealant; if u do this make sure the can states it has ALUM as part of it makeup.

Lost Torque?
-Old thread in/on the block-studs-nuts
-Paint or filler compressing under the Washer
-SS Nuts being over torqued and thread collapsing/galling.

-Old Stud stretching.
I jokingly say that by the time a engine leaves my shop it been torqed 123 time.

Sadly ive had a bad surface job in the past.
