Wanted to buy a CompCams 69-400-8 or similar (custom grind on a 69-000-8), but their website says "available soon 2-4 weeks" for the past year+. This is for E85 build and have all the 109 short block ready Anyone know where to buy performance roller cam? Thanks!

interested assuming Fubar1425 doesn't purchase the heads, etc. oops - missed the date, lol - odd that there is only one P4S entry from this year and everything else is May 2020 or earlier...

Driver's side interior door handle broke last week on Turbo T. Replacement wanted. Thank you!

Blazer upgrade, so I don't need these anymore. 130k on the car these came from. Both calipers need rebuild, so only worth core value. I don't have the passenger side spindle You pay for shipping by sending me a shipping label and i will pack/send you the parts.

Stock long block - never touched the knock sensor - trying to track down a snapping sound coming from engine under boost (>8 psi). Started a month ago and have tested several things: coil and ign module, plugs replaced, fuel pressure is good (under boost), methanol spray is working, no leaks in...

Tried this in the Brakes and Suspensiin forum, but no response so hitting larger audience. planning out the dual piston caliper brake upgrade after looking through several threads. There won't be 2WD Blazers within 1000 miles of me, so local junkyards won't help much. Called Napa and thee have...

Planning out the dual piston caliper brake upgrade after looking through several threads. There won't be 2WD Blazers within 1000 miles of me, so local junkyards won't help much. Called Napa and theY have everything but the Spindles (same with Rock Auto, Summit, etc.) Who has the 98-02 2WD...

With strong acceleration (15 psi boost on stock turbo) heard a loud bang on 2-3 shift and lost all F,R gears. Took transmission out for rebuild, and builder said OD planetary failed (this was supposed to be 750 HP build and I'm no where near that). Got the rebuilt 200r4 in a couple months ago...

my car came with digital dash, so has a boost switch that lights up dash bulb for Turbo Power. Swapping in a 3 bar MAP for Alky. I don't have the screws or bolts to attach the MAP to the mounting bracket - what diameter and pitch are these screws? (guessing something metric, possibly M6 x 1)...

I've found a few threads talking about cam/crank timing and measuring signals with an oscilloscope. Unfortunately, most of these are so old that the picture links are dead and gone. For instance this thread Or several old posts on this thread in turbobuicks.com by GnJones231...

Hello- Started up the car this morning and heard a light knocking sound when under the car, cannot hear the sound in the car or looking into engine compartment. At first I thought it might be a rod knock, but it is loudest at the torque converter. I have a stock converter (D5), Trans was...

Pulled the old cam shaft to replace with TA hydraulic flat tappet. The journals are 0.0015" larger diameter than the stock cam, and it is pretty tight fit. Anyone else have this issue, or know reasonable fix? I think the fit issue is significantly impacted by replacing the front cam bearing...

Hi! Replacing my 140k stock camshaft with 206/206 hydraulic flat tappet, lifters, etc. After pulling the stock cam I noticed the front cam bearing has the typical grooved wear pattern, and should be replaced. Searching through various threads I have found that replacing the front bearing is...

I've looked at several threads where people have reported similar symptoms, and the Buick shop manual discusses the identical issues: - Start-up cold start = clacking, rattle sound under valve cover that goes away after a few seconds of engine operation from cold start. - rattle and clacking...

Posted this question and pictures in the Engine Tech forum, and received some helpful advice: http://www.turbobuick.com/forums/threads/cam-button-in-stock-timing-cover.404651/ Other opinions on the usefulness of 135kmi stock cover with metal loss due to years of abrasion from plastic cam...

I've read several threads on upgrading spring-loaded camhaft thrust button to spring-loaded roller version when removing front timing cover. I bought a NAPA 9-5189 spring-loaded roller button for this purpose. Car is TR @ 135k with stock camshaft, and had stock cam button with plastic head...

My car had a oil leak near the rear section of the oil pan, but i could not tell if it was oil pan gasket or rear main seal. i see oil drips in the transmission torque converter cover and on the fly wheel. Rear main seal area looks clean, but it is hard to see. Because i did not see any obvious...

DS header had a pretty large crack on #5 tube. A friend fixed it with his TIG using nickel filler (he stated that nickel is ductile and would relieve stress from the weld better than some other wire choices). he also welded a brace between 3 & 5 tubes as suggested by multiple other posts...

I've read a few posts on possible causes when IAC = 00 in P,N. Could be vacuum leak, TPS >0.46, bad IAC sensor, throttle blade adjustment. My car has TPS @ 0.44 and new IAC sensor/actuator. When engine is cold and trans in P,N the IAC counts are 30-40 upon start-up, and the IAC counts gradually...
