Good morning,
I gave my brother in law a quick tune up last night after he complained about the engine in his 1992 Civic running rough.
I was able to change the plugs, wires and cap in the time allotted. As I often find, the screw holding the rotor on was stripped, so I'll have to give that another go when I have more time.
But, when I pulled the plugs, they had a heavy, crusty white deposit on them, all 4 of them. Clearly something is wrong...and the engine is drinking coolant now as well as oil...The plugs were replaced before I bought the car, as when I pulled them, they looked brandy new.
When we first got the car, I ran a UOA and found no coolant in the oil...but now I'm concerned again.
He's running Rotella 15w40 for now...but I'd be very suprised if that would lead to these deposits. I'm thinking he's burning coolant now. Could anyone confirm this?
Thanks,
Bogatyr
