I'm pretty certain you are correct. My tensioner looks good but, a past owner may have replaced the tensioner a long time ago and piece fell into pan? The metal is an exact match. Thanks for the help!!!

Hi, I blew a headgasket on a 86 GN, I removed the engine to fix head gasket and regasket the entire motor. After pulling the oil pan, I found this 3/4" 4 sided piece metal. I have no idea what it is, I doubt it's part of a ring...it's to straight and I don't think its a wrist pin retaining clip...

Yep, for sure. Looks like engine coming out. Owned car for 12 years so, its had to happen sooner or later. Thanks everyone for the responses.

I was hoping dimples but, i checked a good cylinder and it has no dimples....yikes! The mystery continues.

Hi, I have a 86 GN and cylinders 1 & 3 aren't firing. Confirmed I have spark, fuel injectors acting funky on these 2 cylinders. Havn't dug further with injectors since I discovered cylinders 1 & 3 have 30psi confirmed with compression tester. This then made me send my inspection camera into...

Hi, I'm looking for a bigger then stock cat back / test pipe back exhaust? I'm in Conn.

Update: I cleaned the valve body and adjusted the TV cable a little tighter and the trans works perfect. I didn't bother with the cheap shift kit, not worth the hassle. It turned out to be a very nice stock trans and the lock out converter works perfect in OD. So, it's good enough for now...

Thanks for all the responses, Bison, good to hear from you, you rebuilt the turbo for me a few years ago and it's still running strong! Anyways, back to the topic. I'm going to drop the valve body and give everything a good cleaning. I'll take pics of the valve body and post. I'm going to...

That's good info, thanks. I will probably drop the valve body and take a look / clean. The trans sat for a few years and both TV / Dipstick holes were not sealed but, in a heated garage. There wasn't much debris in the pan when I changed the filter prior to install. One mistake I made was...

Hi, I installed a used 87 200R4 into a 86 GN. The used trans is a AC Delco replacement trans out of a 22,000 mile GN that was wrecked. I installed the trans about a month ago and it drove great, my father wanted the trans to shift a little harder so he messed with the TV cable while I was not...

I made contact with Boost via facebook and they stated they were out of cables. Would of been nice. Thanks for the recommendation.

I installed the adjustable cable today, the cable was a used cable but, in very good condition and works well. The car runs great when it's cold but, soon as it warms up, when I give it some throttle, the car bogs and wants to stall? I'm not sure what that is, the engine runs fine while idling...

A friend gave me a used adjustable cable and I'll install it tomorrow. The Highway Star cable tran end is no longer completely flat, I think that may be part of the problem and I'll also bend the hook so it will lock into the cable more securely. I'll update post when after new/used cable is...

Thanks, I'm looking for a cable. Only folks that make them are Highway, Kurban & Gbody. Hopefully I could find one on craigslist.

Hi, I just installed a used low mileage 200R4 trans into a 86 GN, I'm having a problem with the TV cable, the cable keeps slipping off the tiny rod that hooks into the TV cable at the transmission under the car. The TV cable is a Highway Stars cable that I bought in 2016 and seems to be in...

Hi, thanks for the replies. I haven't had a chance to look at the car today. Yep, I was thinking the paper clip method was worth a try and I'm gonna check all the ecu wiring. It's been super cold here in CT the past couple days so, hopefully it warms up and I'll dig into it. I have another...

Hi, I have a 86 GN and today my father was driving it and he stated the car was running weird and the check engine light cam on. He got home and the car would not start but, 20 minutes later it started but, not running right, a little rough but, drivable. I connected the OBD scanner like I have...

I am looking for a new GN picture of the cars sitting on the dealership lot back in 86 or 87? I seen many pictures like this on goggle images a hundred times and now that I need one, they can't be found. Does anyone know where to find one of these pics??

IDK about GM anymore, I think they are crooks these days, a new Z28 is 75 fukin grand...which is BS so, what kind of crazy price would they want for a GNX and would GM/Buick actually make a proper GN or will it be a stupid version of a Caddy.....anyways, GM has really gone down hill since the...

Yea, I could of made my statement better/clearer but, at the begging of my previous statement....I mentioned what I thought a GN should be for the next GN generation but, "it's just my opinion....I am one out of a million opinions". Anyways, When Buick went from their top performance car...
