Default So, what does the intake look like @ 260,000

Supercharger intake

tb intake

tb exit (compared to 99 tb, ready to install)

Me, trying to get all the antifreeze out of old intake. Next time I'll just go staight to removing it.

Old intake, sc removed

Both sides of the lower intake


Engine valley with lim gaskets



"new" lim

sc nose with "old" coupler

old on left, new on right

more sc pics


rotors





We ended up reusing the old coupler, before you start screaming, there was no reason not too. Haro wants my new one, and there is ABSOLUTLY no play in the old one. In fact, the old one is so tight yet that it had to be pulled off and pressed on. Meaning it will not slide off of the pins.

260k on a perfect coupler

so does all this work count against your 260k perfect miles claim

Yeah, I was pretty dumbfounded at how tight the original coupler was.
The LIM and the ports on the heads definitely benefited from just the cleaning, and then the light bit of smoothing the inlets on the heads and the more extensive polishing of the LIM and SC should really add some life to the car, as if it didn't have enough in it already.

I have this week off and I picked up a couple bits for the Dremel (should have just bought what you had left over), but I still need a flapper wheel. Anyhow, with the week off and my cousin just called to ask how hard it is to do almost the exact same thing in his 98 Regal GS as his LIM gasket is leaking coolant, so I am going to be dropping the LIM off at my brother-in-laws shop for him to put it in the parts cleaning bin, and then tomorrow night I am going to smooth the inlet and outlets on it, pull the 99 SC apart and clean that up a bit, and Tuesday or Wednesday when his new metal LIM arrives at the dealer we will tear his down and put the new goods on his car, much the same as you and I did, only this time it'll be during the day.

No, as there were no faulty parts about all we can detract from his claims is he replaced the LIM gasket and SC and TB gaskets as well, but none of which were bad.
He'* really just putting to test the moving parts of the engine now, of which only the rocker arms and valve springs are all that has really been changed, but still rocker arms and valve springs are so rare it hardly can count against him.

Just great, Travis. Now that car won't run any faster than 14.5 and your gas mileage will go to $hit! If it ain't broke, don't fix it!










(Jusk kidding, buddy... I think a LIM gasket job was due on that beast. She should serve you well for many miles to come!)

Seems like a lot of sludge in the valley, maybe I'm wrong

Not too bad actually. Very comparable to the amount that was in the LIM off my 99. Same for the SC inlet. The LIM off my 99 only has 114k vs his 260k, so it is very impressive IMO.

Yeah, what kind of oil were you using and what kind oil change intervals were you doing?

Personally...having pulled many of these 3800'* apart.. I think the valley looks average, or better than average.

Let'* compare my teardown at about 140K

TB

SC Inlet (Willwren..see the boring off in the Southeast/Northwest)


While Travis has 100+ more than mine.. they look pretty darn similar.
