.happens only when cold startup,  when engine warms up its all
Gone!!.....so far new tune up, new tranny, new Timing belt , always 93
octane gas.( should i go lower?). Altough i got a leak on the valve
cover( seemed to have stoped anyways) rear valve cover passenger
side...is it OIL  pressure not lubicating the internals (10-30)? maybe
cuz i have  a valve oil  leak? ....any help.inputs.appreciated.
