Hello all, I noticed a Deville recently for sale on Ebay.In the ad the guy states he is a mechanic and repairs the North* with his custom designed studs..C-Guard Super Star Studs I believe he calls them..Has anyone ever had any experience with this guy whether it be good or bad?

Re: Super Star Stud's...Anyone Ever Use Them?

You having engine miss/overheating problems again ???

Never heard of him/them. Any of us could commission a set of studs for any engine. In today's computer machinery world it's a piece of cake - BUT the trick is to get the right materials for the right gasket sets for the right engine under the right conditions. Very, very few individuals have the perseverance to do the R&D on a limited production item like this.

For a small look at the specialized fastener world, look at the ARP website. http://arp-bolts.com/ If you're an insert person as opposed to a stud person, ARP makes a set of VW cylinder studs that are the cat's meow with Norm's Inserts - www.huhnsolutions.com

Any other (stud) application for a Northstar should come from the (experienced) www.northstarperformance.com guys.

Start to get your C-Guard feet wet here.................(from a quick Google search)

No overheating, engine missing on 2 cylinders only at idle though..Had an issue with catalytic convertor that I let go to long and I think all the heat trapped in motor burnt the valves on those 2 cylinders. On highway it dont miss..

Compression test - engine warm, all plugs out, injectors disabled, throttle blocked wide open. Roll the engine 3 times for each cylinder pressure test.

If one or two cylinders is low, a teaspoon of oil in each, roll engine to distribute, retest: Pressure rises - stuck piston rings. Pressure stays about the same - burnt/cracked valve(s).

Your compression pressures should average somewhere near 150 psi with all cylinders within 10% of the mean.

I seriously doubt that a partially clogged cat would burn a valve .................The exhaust valves transfer heat from the valve head to the seat each time they close. Depending on which engine has the miss (1996, 2000 - different engines), it could also be plugs, boots, plug wires, ICM connectors, coil cassette coil tower inspection, coil base cleaning, coil cleaning, ICM base ground, boot inspection.
