The only other problem with the tires is if they have sat sationary for a long time they flat spot and will cause vibration. I think the ball joint theory is bs, mine is as solid as a rock with zero stearing or handling complaints.
Assume new engine:
1) try to twist distributor with hand, if it turns reset timing and get a new distributor hold down clamp which is more robust and does not plastically deform.
2) Check clutch slave cylinder reservoir for fluid. The POS wilwood is known to leak and should be taken apart and reassembled with seal all by the o-ring.
3) Ensure ball joints have been greased by greasing them.
4) check all suspension bolts, caliper bolts, header bolts, sidepipe to header bolts.
5) Change the $4.00 yellow
oil line to your
oil gauge with braided stainless, The yellow will leak at the connection at block, it is just a push in connector, aka, fuking joke on 45k roller. search this forumn for part number.
DONT TAKE THIS THE WRONG WAY. All Cobras are garbage compared to modern day GM's and Ford's etc. Bolts come loose, reservoirs and components leak, **** fall off them etc. They are like a high priced whore, fun to paly with for about an hour a week but you tire of their sheet on a dailey basis.
