Oil Squirters In Valve Covers

[olblue75]

But wouldn’t also depend on the jet size in the valve cover an I’m sure aftermarket heads would enlarged and radiused drain back holes.

I'd read the replies in this thread before going any further if I were you. I think you're going down the wrong path given what your car will encounter on a track day and autocross course.

The valve lifts and springs we use on these engines with the stock rockers is nothing compared to a full race engine. I dont think the oilers will help anything really.

Not worth the trouble ,and may cause more problems than it cures.

I read that thread last week and seems like it could be a benefit but the draw on the system could be a issue. But plans are to run a high volume pump. I already have a external oil cooler that holds a extra half to 3/4 of a quart of oil. I also asked best lace to plumb it and was told to use the return line from from external cooler using a -10 adapter with 1/4” NPT port to -4 AN fitting up to the valve cover, so if I remember correctly -4 is 1/4 ID so not like there’s that much oil being diverted. I wish there was some kind of data that would quantify how much extra oil is used in this kind of setup. I have seen full blown valve covers from Comp Cams that the oilers built in the cover to lower valve cover adapter plates with the oilers in the rail of the adapter.

The reason why there is no data is because every system is purpose built with a specific engine, car, and race in mind.

They aren't really utilized unless in extreme cases like land speed racing on the salt flats where your race ready dry sumped huge solid roller cam SBC will spin at 8000+ rpm for 2-3 miles flat out in a chassis/body with very little in the way of cooling due to it basically being sealed to promote aerodynamics.

Again, not suited for what you will be doing.

What about the Silver State Classic 90 miles of flat out pedal down within in your class limitations.

There are a few guys here who have done it. Go ask them if they run these valve spring sprayers.

I'll save you some time though: they don't. The reason for that is because you aren't 'flat out for 90 miles'. You get put into a class with an average speed you try to stay at and a top speed you're allowed to hit. It's a high speed time trial basically.

Cornerspeed92 is a member who has run it and documented it well.

I'm not trying to say this doesn't work. It does: Outlaw racers say they can get another 6 races out of their valve springs when using sprayers. But those engines run huge solid roller cams and can benefit from the sprayers. All you will be doing is relocating the oil in the sump to your cylinder heads without adding some sort of scavenging pump (vacuum pumps are about a grand for a good kit and then who knows if it will fit the 5th gen so more $$$).

Your time and money are better spent increasing the efficiency of your current cooling system. Add as big of an oil cooler as can possibly fit and add in the biggest aluminum radiator and no thermostat if you're really worried about heat. Hell, add in dual oil coolers if it'll help and you can even remote mount the filter to cool it as well.

Good luck dude. It is your car so do what you want but there are way better options to keeping the valvetrain cool than this.

All makes good sense so think I’ll drop that project and look at a bigger cooler and remote filter mount. The sprayer deal would have cost almost 800 bucks after it was over and done with. Thanks everyone!!!

With the ls the problem is usually too much oil in the heads. Oil up there is not a problem, draining it is.

Some of my hard core road racers would fill the heads enough to have it pour out of the breathers.

Better to invest in a good oil cooling system.

As many have mentioned, there are probably better options out there....

I run valve covers with spring sprayers. There is a -3 port on the back of the valve covers. A line is run to these ports and is supplied by my dry sump system. Oil is supplied continuously while the engine is running. There is no check valve in the system as it isn't needed. These valve covers were supplied with the AllPro heads.

This is to cool the springs for a very large lift solid roller cam and we are spinning the motor to 9000 on mile long land speed races...

When taking the oil volume supplied at say 50-60 psi WOT high rpm pulls, via a 3/16 ID tube, divided into 8 or 16 spray tips, you are actually looking at a moderately small volume and pooling in the heads shouldn't be a consideration. It would be an easy fix if it were so. We supply 80 psi oil pressure at WOT and high (8000-9000) rpms.

I tend to think that a good oil cooler, keeping the circulating volume as cool as possible, might be the best option. With the moderate lift and limited rpm's, there are better options than spring sprayers. Metallurgy has come a long way and quality springs can handle the stresses imparted in most cases, even in the Silver State or Big bend open road races....



I apologize if you already know this, but as was mentioned, these races are more a time trial than a flat out race. Every driver has to earn the higher speed classes. Hypothetically you might be put in a 110 mph class, with an average speed goal of 110 mph, and a top speed allowance of 124 mph... or even a 105 or 95 mph class as a first timer racer. Within the touring class as with others, the tech speed is determined by the safety equipment on the car....

Good luck with your racing ventures.... It's fun, and addictive....
