Stroker motor oil pressure problem - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Foster78 · 03-13-2016, 04:44 PM

Anyone out there running Stroker engines? I put a 418 Stroker in a couple months ago and have low oil pressure at full operating temp. Need to know what the stock oil pan clearance is to the pick up. Never did check mine. But I think my prob is the pick up is sitting on bottom of pan. I plan to pull pan next week but jus curious if anyone else has been through this with a stock pan on Stroker. I was told the clearance "should" be 1/4 inch and that the spacers on the windage tray measured .215 inch. That would explain when oil gets hot and thick it's not able to get through the space. All the usual has been checked. Oil pump x2 brand new ported l99's- o ring triple checked- cam bearing and crank bearings checked- different oil filter brands tried- jus figured someone has run a stock pan on a Stroker with windage tray and give me some feed back.

I dont believe oil gets thicker as the temperature rises. Interested in seeing the solution here.

Yes oil is design as light when cold and heavy when warm.. I'm working on the solution jus figured someone has be through this rodeo already. I really want to find out what gm clearance is on the oil pump to strainer

Who told you oil gets thicker when hot? Yer Daddy?

Ok not sure what's going on in the pics. Did you remove the bottom of the pickup and the screen for some reason?

Here's what I'll tell you. Clearance is 1/4 to 3/8 inch from pan bottom I'm pretty sure. Oil looses viscosity when it gets warm and thus would flow into the pickup easier not harder. If you are loosing pressure when it comes to temp that means oil is flowing through less restrictive areas quicker than the pump is able to build and maintain pressure. So my first question is what pressures are you seeing at what temps and rpm on the motor?

Some other areas you could check that have been known to cause a low pressure problem at temp would be the cam retainer plate. A bad gasket there will bleed hot oil back to the pan through the timing cover. Outside of that and the other obvious ones you mentioned I would look back to the bearing clearances or possibly the oil pan relief.

Well having Had Wong of Wongs performance engineering in Vancouver do mine, he said the special windage tray I bought from Mast made for a stroker was not even fitting right and he had to alter it to keep the pick up right. So you may want to talk to him. Good Luck

If you pull the drain plug you can look through the hole and see the pickup if in doubt. I cut the existing mounting tab and repositioned it.

You are only partially right on the way oil works when hot. A standard 5W-30 breaks down like this: The "W" stands for "winter", not "weight", so the oil acts (viscosity wise) like a SAE-5 weight oil when cold. When hot, the oil acts (viscosity wise) as an SAE-30 weight oil. The oil still gets thinner as it becomes hot. Depending on your bearing clearances, you may need a 10W-40 or a 20W-50. My 416 stroker worked just fine with the stock pickup and oil pan, just had to clearance the windage tray so that the pickup wasn't bound up. I run Valvoline VR1 20W-50 in the summer, and 15W-40 in the cold weather.

Your pressure will drop as you approach operating temp. This is an undisputed fact. Question is, what is your pressure at idle when warm? Should be around 30 and should maintain at least that at operating rpm, preferably 45+.

Running a Stroker here with Stock Pan/Pickup now with about 2500 miles on it. Melling Hi Volume Pump.(Broke in New on VR1. Run RP HPS 10w40) This is the normal Oil Pressure On a Hot FL day.Have never seen it lower. Knock on Wood

Foster78 · 03-15-2016, 12:47 PM

Thanks for the reply! Are you running the windage Trey on bottom of crank?

tadams72 · 03-15-2016, 01:04 PM

Are you still running AFM? Might be a stupid question but if you have done an AFM delete then you are probably running a higher volume pump than is required for your application.

Also, on my 427 strokes with ported Melling 10296, windage tray, pan baffle, properly gapped pickup, and conventional 10W40 seeing hot idle pressure of 40 psi.
