I remember when I rebuilt my car, scott Parker from manhattan motorsports back in the day said that the oil passages were clogged so he "massaged them all" what ever that meant. then he told me that I should use engine flush every other oil change. is this ok to use that often? won't it deteriorate the gaskets and cause oil leaks in time? what do you guys think?

The only detrimental outcome I've heard from using stuff like that is that it removes all of the contaminates floating around or stuck to your internal engine parts, and then proceeds to jam your oil pump up pretty well(after a while).

I read an article about partial clogging of oil passages and did notice a tendency of the engine to need a reduced quantity of oil after a change. I tried the STP flush and it did seem to take more oil to bring the crankcase up to full. I have done this twice (once a year) thus far with out any noticeable problem.

I think this was probably more of a problem with some of my old V-8's oil pumps and engines than with foriegn cars. If you want to keep sludge to a minimum,try using something like Rislone engine treatment at each oil change-it keeps your engine internals clean.

There are revised cam oiling tubes from Nissan for the 91 SE-R. I dont remember if it applies to any other year. They have slightly larger passages.
I tried to find the old posts from the se-r.net archives. They are currently down for their weekly update.

Here are the part numbers for the revised Nissan cam oiler tubes.
15108-53J03 tube assy. with discount $22.09
15108-53J13 tube assy. with discount $22.09

The person that posted this had a 95G20t auto that was having sludge problems. But I dont know when the switch was made for production.

I would trust these more than drilled out ones, and they are not that expensive.
