Just finished my little "engine" project. It all started from a desire to replace leaking valve cover gaskets, and ended with...
1. Both valve cover gaskets replaced
2. All injectors fully rebuilt and ultrasound cleaned. Found that one injector (that was leaking) didn't have a bottom seal at all...
3. New plenum gasket
4. Cleaned cold start injector (ugh, no wonder had to turn it for 3 sec to start when cold - it was barely visible through the carbon). Dealer couldn't get a new gasket (only to order from Japan) so cut it by myself from the gasket paper.
5. Cleaned injector seats and intake plenum. Some of the cleaner "leaked" to the cylinder When started first time it smoked and stunk for a few minutes while burning and spitting out the crap from cylinders.
6. Because I was there and plenum was off and clean I couldn't help but paint it in bright red Looks good though
7. PVC valve and grommet replaced. Valve was OK but the grommet was leaking a bit and was stone-hard.

A few tips for someone who is planning to do this. Apart from the obvious (mark all hoses with numbers from both sides, use masking tape) use anti-seize compound on all "hot" bolts - I found some of them were baked on good. Also I found that the only cleaner taht WORKS, I repeat - WORKS, was not the carby or throttle body cleaner (one would hope!) but GASKET REMOVER. It is a bit more expensive but worth it. This stuff foams up when sprayed, needs 5 minutes or more, but man does it remove baked-on carbon! I found that carby cleaner is only good on "wet" carbon gum, but it does very little on baked-on stuff.

Anyway, my truck is running again and I am very happy On to another project

Attaching a couple of pictures of my engine bay now.

 

How many horsepower did you get from the red paint? Looks great!

 

At least 10hp The best mod I've ever done
