I have seen a lot of 1990 engines and damn they are really clean....i want to know what product is the best to clean the engine on my Z...it was sitting for 2 years and dirt is really caked up on it...pressure washing didn't work....can someone help me
I have a Kartcher pressure washer and I've used it on my 300zx TT without any problems. I used Simple Green and kept the motor running while hosing it down. Yes there are exposed wires and the connectors get brittle and crack with age and heat that the engine generates. I had to replace the entire engine harness at about 200,000 miles so my connectors are still in pretty good shape but Mike's caution is worth noting if your harness is high mileage and old.
