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 of Caspers) "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".
 
The cam sensor its self ends up with shaft play and sounds like a bad/loose lifter but really no other way to tell unless it is out of the car where you can check it. The bronze bushings & wave washer eventually wear out.

One thing about cam sensors no one really thinks about is "Oil Contamination", by this I mean if you have bearings that went bad in a previous engine that bearing material has now been pushed all through the cam sensor speeding up the wear process.



How to tell if the cap, interrupter ring or the cam sensor it self is bad?

The caps can "crack" allowing moisture in which is not good and can cause the car to act/ run funny, the caps can simply go bad or the interrupter ring can end up cutting into the cap due to excessive play all of which will make the car run like crap or not at all.

The interrupter ring has a tab that breaks off which has caused a loud "Pop" and then the car dies, runs like crap, small backfires and has been known to cause catastrophic engine damage!

The cam sensor it self wore out? They will make a sloppy lifter noise, can cut into the cap and ruin it, cause drive ability issues, and more.

Simple solution is to actually take it out and inspect it "Before" it does damage to your engine or starts causing issues! $75 is cheap insurance and Way cheaper than a new or even used one so why not be safe?

Just a reminder that now is the time (over winter) to have your cam sensors rebuilt while the car is down! We had a worn out cam sensor and one we rebuilt on display at BG and Many people were shocked at the difference between the two.

Just show them how purty the rebuilt one is Scott.:D He can do that as well if you want to have a shiny looking part rather than the crusty looking stock one.;)
 
If your Cam Sensor has a broken cap, broken gear, or the tab is broken on the reluctor ring, that all can be replaced!

We are also working on rebuilding the distributors for the V8 crowd too!
 
We recently had two cam sensor bodies come in for a rebuild that were so worn down nothing could be done with them and we are not about to start stacking washers to take up the clearance. So we are in need of some cam sensor bodies if anyone has some laying around.

Note: If you have a cam sensor with excessive "End Play" the first thing to check are those feet/tabs! If you have one like the one pictured on the right in the picture you will need a new cam sensor body, we will likely have them here but at least this will let everyone know it will need a new body IF these 5 little (Feet or Tabs ) are wore down badly. There is an additional cost for a good cam sensor body....

Guess where all that bronze and aluminum goes when the cam sensor wears like this? It's definitely not good to have this kind of debris going into your engine and it another reason to have them rebuilt BEFORE they get this far and due damage.

Left = Good body with a 1/8" of length to the 5 tabs .......................Right = badly worn out body with a 1/16" or less length on the tabs.

Are you still offering this service?
 
Scott, what happens when feet taps wear down like on pic above?..last week I removed my cap to check tab and had hard time putting the ring back on shaft. It appears if shaft is worn and ring has nothing to sit on.

Richard told me he can turn down the base and put a cap on those with worn out feet.

Yes, He designed the piece and I have it made...

We now use a HD spiral Roll Pin on all rebuilds at the same low price!

He turned me onto those as well. Every car that comes my way gets one.
 
How much is this service now? I'm interested in having mine done. It's tapping really loud.
