Sunfire creeking/clutch peddle buzz

Test drove a 2003 Sunfire coupe yesterday. base model no options. I found the clutch peddle vibrated while shifting and the car creeked
somewhat when driving in reverse.
Anyone else have this happen to them.?
Thanks in advance
Walt
ps. Anyone with a new ecotec engine have any oil leaks? Does the engine still look clean

Just about every late model Sunfire I drive with the new style Getrag 5 speed has that clutch pedal vibration. We've tried fixing it, to no avail. I don't think that it has any bearing on clutch longevity.

Thanks for the insight Ian.
Do they have a technical service bulletin out yet for the creaking and the buzz?
What do you think of the ecotec.? It is all aluminum and I would hate to buy one and have to replace head gaskets all of the time like the old sunbirds. Do you know if they leak oil or anti freeze as of yet.? Any other opinion on this car?
Thanks in advance
Walt

From what I've heard and had to do with Ecotec class engines, they're very good.
The 2.2 from memory is a European mill, Opel/Vauxhall origins from within the GM tree of command, it's been in use in Vectras for years, along with a smaller version (1.8 or 2.0 I think?) that is in the Astra. Good rep.
And the other Ecotec here is a disguise! Ecotec my arse, it's a Gen2 3800! :-)

Not that I'm aware of. Usually very few people complain about the pedal vibration. We get a lot more complaints about the standard transmission being noisy in 1st and 2nd gear. GM originally had us overfill the transmission by a quart, with Saturn spec trans fluid. Of course that did nothing, why they would imagine it would is beyond me. Plus the obvious fact that the next time it was in for an oil change at any place other then a dealer, the tech would (rightfully so) think the trans was overfull and drain the excess fluid out.
Now they have the proper fix. We are pulling the transmission out and installing some special washers that sit between the syncro ring and gear to keep the rings and gears from rattling. Interestingly enough, even though you hear the noise in 1-2...the problem is really the 3-4 gears.

In actual fact, the all aluminum engine is probably less likely to have head gasket issues as you don't have the head gasket attempting to seal dissimilar metals. That's always been the problem with an aluminum head sitting on a cast iron block like the sunbirds and cavaliers.
I don't know a whole lot about the Ecotec engine, but I do know that Saturn ran them for a few years before the GM lines got them. They are designed much like the Northstar engine. They have a split crankcase, and the cylinder head and camshaft layout looks to be along the same lines as the Northstar, the inline all aluminu 6 cyl in the Trailblazers, etc. I imagine they will have variable valve timing in a couple of years as that technology will probably move quickly into engines other then the I6 and the XLR Northstar.

So far, haven't seen any problems with the Ecotec. Listen, the Sunfire/Cavaliers are your typical econobox. Overall, I don't see a problem getting to 100K miles with very few problems.

My nieces boyfriend has 96 Cavalier Convertible 2.4 and it just turned over 200K and the only problem he has had is the convertible top is now starting to leak.
