I recently installed the trickflow trackheat kit on my 93 5.0. The first time i started her up the timing chain blasted through the timing chain cover and I bent 4 intake valves, metal was all in my oil pan, It was a disaster. I sent everything back to trick flow and this is what they said:
Chad,
After both visually inspecting & dimensionally checking everything that was
sent in, We have determined the reason for the failure to be insufficient
camshaft endplay. As you are well aware, Endplay is the ability of the
camshaft to move back & forth in the block. The minimum is .001", The
maximum is .007".
We are willing to repair the heads & sell you the required components at a
reduced price. For example:
Intake valves: normal cost $12.95 each, I will sell them to you at $8.50
each.
Head install gasket kit: normally goes for $90.95, Your cost would be
$64.95.
Timing Chain: normally goes for $63.39, Your cost is $50.00.
Camshaft: normally goes for $159.95, Your cost $115.00. (Your camshaft is
reusable but would require refacing the end of the camshaft to make it so.
We do not have the capability to do this operation in house, Sorry...)
If you want, You can use a standard double row timing chain, That is not a
problem at all. If you are interested in a standard double row chain, I can
sell you one at $25.00...
Please make sure your friend verifies the camshaft endplay in his block
before final assembly!...
