GNS Performance Turbo Regal Cam Sensor Rebuild Service

​

We are proud to announce that we are now rebuilding cam sensors for the 84-87 Buick Turbo Regal. Why buy a remanufactured cam sensor when you can save $100.00 and have us rebuild your old one back to new? Gary Tarwater & I spent a great deal of time at Richard Clark's place learning how to rebuild these "Properly" with the proper jig. So, you can rest assure your cam sensor will be better than if you were to buy a remanufactured one from a large parts store. At this time we do NOT replace or repair the cam sensor Caps.

NOTE: We will be in Bowling Green for the GS Nationals so we will not be able to rebuild them during that time. If you need one rebuilt before then you must get it to us before Oct. 12th.


PS: Please remove your cam sensor cap, we will not need it to rebuild your cam sensor!

Rebuild Cost: $80.00 - This includes the return shipping!

Rebuild Process:

• We completely take it apart and clean it inside & out.
• We clean the cam sensor gear.
• We then balance the top reluctor ring, which was never done on OEM cam sensors. (Same as Richard Clark does)
• We replace the two Bronze shaft bushings in the cam sensor body.
• We clean the coked-up oil off the cam sensor shaft prior to re-installing.
• We install a new wave-washer and shim-washer.
• We clean the soft packing material under the reluctor ring, oil it and re-install.
• We then install the shaft with a new roll pin so once we are done the internals are completely rebuilt with brand new parts.
• The cam sensor is oiled during assembly and checked for proper clearance before it gets returned.

Parts Replaced:

• Wave Washer
• Shim Washers
• 2- Bronze Bushings
• Roll Pin

To get your cam sensor rebuilt simply send the cam sensor to us with $80.00 enclosed and it will be rebuilt and sent back within 4-6 business days.

Please send it in via US Postal Service to this address:

The cam sensor is a part that seems to get over looked most of the time as long as it's still working and doing it's job but in reality it has several wear parts in it that will eventually wear out. There are a lot of these cars out there with 100,000 + miles on them and all of them are 20+ years old. The cam sensor shaft has been spinning all those miles on two bronze bushings and a small thin wave-washer for end play. These items do wear and end up making the cam sensor shaft sloppy and noisy and eventually fail which in some cases can be catastrophic to the engine. Many of us out there have bought a used cam sensor and stuck it right into our engine and they probably work just fine, No more worries because now anyone can have theirs rebuilt for a fraction of the cost of a new/used one.

Oil Coking inside on the shaft is also something that occurs after time. The ones we have already rebuilt had a bunch of oil coking on the shaft..

Yes the "cap" can also go bad on these but has way less wear parts than the actual cam sensor itself. Excessive end play in the shaft may allow the ring to hit the top of the cap slot which can/will ruin the cap.

Side to Side play isn't good either and has been know to cause drive ability issues in some cases.

(Quoted from John Spina) "Cam sensors will fail if the end play of the shaft gets excessive, especially if it cuts into the underside of the cap. High mileage cars are susceptible to this and I've seen it happen quite a few times. Every die-hard GN owner out there should have in their possession, a spare cam sensor assembly. Or two. These are "wear" items....so every 50,000 miles or so, they should be routinely replaced. Just. In. Case".

Sweet for this, I will be sending you mind then. Any tips on installing it back in, do I need to put the engine in TDC or is it just slide right back in with no fuss or any particular details?

Before removing it you need to put #1 piston to TDC and then mark the cam sensor location somehow and then remove it, once you receive it back then install it in that exact way/spot and the car should start right up...
