Hello Rennlist,
Had a question for the community regarding what other maintenance is possible while I am doing the Cam Tensioner and Chain Replacement. Whilst I am under the hood, I plan on doing the first oil change too, but, as always, my mind began to wander as to what else I could do............$$$$$
Things I would like to do:
1) Front engine seal - I have a slight oil leak and my mechanic said it was most likely the front engine seal. He suggested to do it when I change the belts, but those were done 9K ago so I figured this may be a good opportunity since they are coming off for the cam job.
2) Throttle body inspection? I have heard a number of people say that the butterfly movement can be limited with time, and you should inspect to ensure full open throttle when the pedal is depressed...
3) Spark Plugs and Wires? Time to replace/upgrade? Is there really any benefit?
4) Injector cleaning? I know there are some additives that clean the injectors to an extent, but didn't know if this was a time to inspect them to see if they need further cleaning... also, any suggestions on injector cleaner additives?
5) Valve Cover clean / paint - There has been a lot of talk recently about re-finishing the valve cover, and that obviously made me green with envy... I would like to limit myself to just cleaning it, any suggestions on cleaner while it is off? I would like to send it out to get re-finished / painted, but I only have a limited amount of garage time...
6) Anything else the all-mighty Rennlist can think of?
As always, I appreciate the feedback, no matter how critical it is!
Cheers

GD, if you really need to, do all front engine seals. You can actually do the chain and tensioner pads without removing the balance shaft belt but if you really do plan to remove both belts, removing the rear belt cover is not that hard.
You need to remove both bs psrockets to get to the belt covers. Once the sprockets are off, you should do both upper and lower bs front seals and engine seal, if they are leaking.
Sometimes, we are better off leaving well enough alone. You can do all this over 1 weekend.
I have always found that getting the injectors serviced is a great way to pick up some lost power. Turn around can be quick and they provide you graphs of before and after. New plugs/wires, dist cap and rotor are also easy to do and will be removed anyway.

Ernie, in the past I have always used Marren Injection in CT (www.injector.com). Turn around is very quick. From when they recieve your old injectors, they take 1-2 business days.
