Yeah, the valve train noise from my SLPs is VERY noticeable. Actually, it is considerably louder than the ticking you have there.
I would still do a smoke test, and check the cross-over pipe joint for leaks, but you're probably fine.

I'll be honest, though, I'll never trust the Plog. I just don't like doing things halfway, and the Plog seems like a bad compromise.

As far as the smoke test goes, you can also suck some Seafoam down a few vacuum lines, and that will shoot white smoke out of just about every exhaust leak you have.

This works amazingly well. When i seafoamed my top end thats how i found the leak at my crossover pipe.... that i still need to buy the donut gasket for....

Yes, looks like I am going to perform this tomorrow and see where it goes...I never even thought of this lol


Thanx ALOT for the advice guys

Make sure you have an oil change and new plugs handy. Sometimes an O2 sensor, also.

This is very true. Good catch.

Which 02 sensor are you thinking? The one behind the cat?

I just recently did new plugs, but I can always do new ones again, its no biggy. And I was planning on switching over to synthetic anyway before I got my car back on the road so why not do it now

We pre-96 L67 people know of only one O2 sensor. He probably meant both, but usually I'd imagine you'd have some issues with the front one before the rear sensor. Pure synthetic oil would be great to use on such a car now and throughout its lifetime. Seems like you drive your car hard, so please make the switch. If for some reason you've had your car running rich or lean, your spark plugs have probably had their lifetimes shortened. Pull the front ones and one rear plug (or all 3 if you have the time and patience) to see if they look healthy and generally similar.

Awesome...Thanx for the tip, Im deffinatly going to take care of that...

Where is the front 02 located?? I hate this stuff lol I literally know nothing about engine work

The rear O2 shouldn't be affected. All the goop should burn off in the grid of the cat, preventing the rear from getting hit.

The front O2 sensor is in the top of the rear exhaust manifold. It looks like a spark plug. If you're not due to change it yet, buy a plug and put it in before the seafoam, then put your O2 back afterwards. DISCONNECT yours before you start, don't just leave it hanging there. You'll throw a code, but the car will run with default tables.
