Hey Guys,
Gen 3 V, done 38,000 kms.
As part of the TB sync, i guess cleaning the throttle bodies is a good idea. Especially where I live, is very dusty, and the gas sometimes might not be the best (have just started using a liquimoly equivalent of lucas upper cylinder cleaner). My steps will be:
1. Check existing manometer readings and make a note.
2. Clean intake valves alone
3. Check readings again.
4. Adjust the left bypass screw to see if the readings come to spec.
5. If readings are too low/not to spec, remove entire TB assy and inspect bypass screws if they are choked - clean the rest of the TB while at it.
6. Reinstall, clean bypass screws/install new bypass screws
7. Take readings again.
Does this process sound right?
1. If I find the bypass screws on the TB assy black and choked with carbon, do I replace that whole thing along with the washer, O ring etc? Or Just cleaning both the screws with a high flash solvent and putting it back in will suffice?
I also understand to leave the right bypass screw alone, and adjust ONLY the left (that's the cylinder that fires first), and then hopefully, the right cylinder will readjust itself and calm down to match up with the left.
2. My other question is what if the left does not allow for any more adjustment - already turned out fully? And the cylinders then read about 32-33 kpa on the manometer. What then? The actual reading should be 37.8 kpa.
Many thanks,
