OIL LEAK IN GASKET
Because these were brand new engines client was surprised that most of the cyl.heads were leaking oil.
Client and manufacturer demanded a quick fix for this problem. In order to repair this problem i removed all cyl.heads and cleaned and decreased all parts. After receiving all new ordered parts I started to rebuild the 1st engine which could be tested on the test bench. After completion of the 1st engine, I prepaired the second engine to under go the same procedure.
