engine wear

I just got to get those last three little bolts out and the pan will be ready to come off but the guys in my shop just think I'm being overly dramatic.

That is extremely good news...but does not explain what you seen on dipstick and in oil you drained quite yet unless that is the "Overly Dramatic" Part

Now I know the engine is going to wear and there will be metal in the oil but enough that it shows up on the dipstick?

It's not magnetic however did find a few pieces of metal that stick to my magnet. Took an oil sample which will get sent out tomorrow to see exactly what types of metals I have in there. Till then it'll be sitting in my garage under the car cover till I figure out what my next move is.

Or....Maybe we did not understand that the oil was actually clear when you drained the oil and what you seen on the dipstick was in fact bubbles

But then again...you did say your oil pan bolts had dropped out....almost half of the fourteen 8mm bolts

So it sounds like the engine got low on oil and the lifters got noisy. Should be ok.

My earlier comment about looking at dirty motor oil in good light still holds- there's all kinds of micro particles that may or may not mean anything.

Got the pan out and well there's nothing unusual. Just a lot of dirt. Between the heat shields, jacking the motor up and everything else I can already see that it's going to be twice as much fun to put it back in the car. So if anyone has tips to get it back in it would be greatly appreciated. And note to self I need to go buy 1/4" swivels

I use a bit (small bit) of Permatex Super "300" Form A Gasket on both sides of the oil pan gasket where oil is involved (making sure all surfaces are dry before using the Permatex)

Jerry's pan gasket for the 90'-92' requires a new "O" ring which is the same diameter but thicker for the oil pick up. Just make sure you keep that "O" ring in place as you position the oil pan with new gasket.

I use Blue Loctite on ALL Oil Pan Bolts.

hope you get it back together soon. hope to see you out and about

[90ZR1#1221]

Would you recommend getting two gaskets since its my first time putting the pan back in? In case I mess one up. Also does anyone make a pan bolt kit cuz I just want to put all new pan bolts back in the car. And is there a torque spec for the pan bolts?

One gasket is enough......I think

On Jerry's page you have the Oil Pan Gasket Installation Guide, Oil Pan Gasket for 90', Oil Pump Suction Pipe "O" Ring.

Jerry's Oil Pan Gasket and Associated

Typically.......6 mm bolts go 89 in-lbs (three in front of Oil Pan)
Typically.......8 mm bolts go 19 ft-lbs (fourteen in rear of Oil Pan)

Clean ALL Oil Pan Bolt Holes with cue tip and gas or something similar. Use Blue Loctite (242) on ALL Oil Pan Bolts. As you already know, I use thin coat of Permatex on both sides of the oil pan gasket.

The TRICK is balancing that "O" ring in place while keeping the gasket in place at the same time you start and snug up one 8mm bolt on each side of the oil pan. After that.....you are home free

Here are the 8mm oil pan bolts (ten) except those two on each side which are studs that hold the exhaust shields. And except the three front 6 mm bolts. Jerry's oil pan bolts

You need Four Heat Shield Oil Pan Studs/Bolts

You need Four Heat Shield Nuts

For your 90' you need Three Oil Pan Front Three 6 mm Bolts

On a 91' You would have seen a Low Oil Level Indicator on your readout above the radio when you first start the engine. The Oil Level Sensor was not used on a 90' unfortunately for you.

I am still looking for an LT5 Oil Level Sensor as Jerry does not stock those as far as I can tell

Dynomite aka Mr. Solutions: Thank you for the referral!! I will see if I can find the LT5 Oil Level Sensors!!

You can find all of the oil pan bolts at an ACE hardware store.
The torque specs are on page 6A2-88.
Oil Pan to Crankcase Bolt is 20ft/lb.

Jerry my man.......those were Left Clickable Links in RED I call them Descriptive Links.
Anything underlined and especially in Bold Red is left Clickable
That is my story and I am sticking to it.

Oh...and I might add....when you buy from Jerry expect the most professional Packaging of Gaskets and expect two day delivery...Maybe three day if post lady is lazy.

And that Post above is referenced in Solutions under the Heading ENGINE LUBRICATION SYSTEM

Jerry....I looked at your NEW 90' oil pan and that is how I found out I do not have an Oil Level Sensor on my 90'.......and that was a great description of that issue associated with the Oil Level Sensor NOT in production untill 1991 New 1990 Oil Pan

The Oil Pan for 1990, 91 & 92 are interchangable with the only difference being, the 1990 LT5 engine was not equipped with a Low Oil Level Sensor. The extra material was cast into the pan but not machined for the screw-in sensor. As such, the oil level indicator would not be functional if the 1990 oil pan is used for 1991 & 1992 applications

First two photos are of a Brass Oil Level Sensor threaded Connecter and the last three photos are of a Plastic Oil Level Sensor threaded Connector.

Plastic oil Level Sensor 91'-92' Summit Racing Oil Level Sensor

I learn something every day

Jerry.....there is an identical Solutions on two web sites just for your information and both updated continuously
