cam swap

[Shimy87]

Like Steve, I too have contemplated not posting anymore Yes, im a novice. If my questions got to painful sorry but I thought thats what these forums were for. I am an active poster on a snowmoble forum as I have raced and wrenched on them for 30 years. I dont get the " painful novice" tag....people come to forums for help or If they have questions, If I didnt want to help them I wouldnt, but If they listen to my advice or not, I dont get attitude with them.

As far a doing the complete opposite, look back at the thread. I have beat this to death...I have taken 99% of the advice here and followed to the letter, I took Jack Cottons advice on the oil and got major attitude back??? I would have to say he know buicks. Also, im fairly certian any flat tappet cam is broken in the same....im curious whats so special about a buick?

Anyway, as I have also said ....ALOT.....I do appreciate any help I recieve here. I dont know how else I could make my appreciation any clearer.

Rant over

Some Buick guys just like to talk trash, that's all it is.
Let nothing offend you Shimy. Surriously.

Got it back together tonight and completed break in. Ran a little rough the first 10 seconds but then smoothed out and sounded real good, after the 20 min run it idled down smooth as silk. Will dump the oil tommorrow, refill and new filter and take for a spin, fingers crossed that it continues to sound good.

Thanks for the help

Dropped the oil this morning, have a magnetic plug and wiped it with white cloth and it was pretty good, some dust to make cloth grey but that was it so I think im good.....cant wait to drive it!!!!!! Did have a no start issue with cam sensor location but re set it and she fired up....was worried about that hurting cam but seem to be good...I hope.

Keep us in the loop sounds like your on the right track.

Good news!

Good for you! Glad it's back up and running!

Well the maiden voyage was a little shaky. Fired it up and it made an terrible clank/rattle for a few seconds. Got out to look it over, was shaking a bit, but noise stopped so I figured run her. Took off and was ok but didn't feel smooth. went about a mile and stopped again to look it over. Still shaking so I revved it up some and all good on increasing RPM but clicking and rough on let off. Drove it 2-3 more miles and still wasn't right but a bit better. Got home and listened everywhere with stethoscope... .nothing obvious. Revved it up and it would do it on decreasing rpms?  Was fearing the worst so just walked away for a while.  Came back later and started checking things.

The little fan for the intercooler was just nicking the angle plate that mounts the intercooler on the passenger side. Took fan off and fired it up....sounds great, runs smooth as silk!!! And best of all that annoying lifter tick I have always hated is long gone  Don't think that fan does much but I'm going to notch that plate and reinstall the fan.

Weird that it hits now but easy fix

The intercooler fan is only good for putting a groove in your intercooler. LOL!

Plus the weight savings

Thought about this on the way to work, don't think I'm going to reinstall it. The only time I can see it being very useful would be at very low speed and the temp drop with it compared to without it cant be much if any. At track speed the scoop is forcing enough air to make it a non factor.

Issue has probably been beaten to death elsewhere

What? No!

Adjust your intercooler brackets and leave the fan on the cah.

I agree........n ot sure why some people are so quick to just toss the factory stuff aside, but to each there own. I mean it's plastic, how heavy can it be.
Try putting a piece of paper in front of the IC while the car is at idle and see what happens.
Now, as for racing, how fast/hard is it pulling air through the intercooler at 4-5k?? I would think quite a bit. How fast are you going 1-2.......not that fast mph wise but your rpm'ing pretty good and yanking alot of air through the IC via that "crappy" little fan.
