Windage tray?

[RCSConstruction]

Hi everyone.
Motor is a 2000 VP 5.7 GS/SX-m drive.
The old motor had studs for a windage tray and the new 4 bolt main motor does not.
How important is it that I put the oil tray/windage tray back on?
I really don't want to unbolt the main caps.
What do you think?

Try using the old main cap bolts.
Then install the windage tray.
Why do you think the tray was installed in the first place, because it's not important?

Thanks.
To be honest I did not think it was that important. I thought it was just to keep excess oil off the crank that may rob horsepower?????

Re: Windage tray?

You are correct, it does keep oil off the crank.
What happens to the oil when it hits the crank?
How well does your oil pump move foam?

Re: Windage tray?

I had symptoms caused by overfilling my engine with oil which caused my oil to foam. My lifters filled up with the stuff collapsed started ticking like crazy.

Why don't you want to unbolt the mains?

Re: Windage tray?

Well for one thing I could see it voiding my warr. and the other would be a possible shift in the cap if the studs are a tad different. Pure speculation on my part of course.
I don't have the motor in front of me but part of me wants to say that the 2 bolt main and 4 bolt main use different size bolts? Right? Wrong?
Thanks

Re: Windage tray?

Ha, well I definitely don't have them right in front of me so I sure don't know. And I'm confused, wouldn't operation without the windage tray be a warranty no-no as well.

Re: Windage tray?

Got me. They knew it was for my boat and did not put the studs in for it.
Thanks for the help all. I will get it put in even if I have to buy new studs.

They install the caps, then line bore it; if you change caps, or even move them to another journal, or put them backwards, you might have problems.

1- you can just change the bolts one at a time.
2- you don't NEED the windage tray
3- You may void your warranty by fooling with it.
The windage tray strictly scavenges the oil off the crank faster--small performance gain at high rpm (above 3000) but definitely not a required component. Thousands of engines were built without them.
If you can install it relatively easily, then do it. If you can't or are worried then don't. Just my opinion, of course.

Yeah, I think the tray is needed only on a 6000 rpm engine, or could it be to keep the oil in the pan in rough seas?

Re: Windage tray?

Nah, the back of the boat stays pretty stable and the inside of the engine is one huge oil bath anyway. Plus the pan itself has a small shelf built into the back of it to help keep oil from splashing out. The windage tray rides pretty close to the crank and is there specifically to scavenge oil from the reciprocating assembly, not to keep oil in the pan.

Yeah, I only used a tray on a 1970 Dodge Swinger, with a hopped 340.

RCS- having one is better than not having one. Good luck.
