Lifter bore grooving tool

[Belgian1979]

Would like to know your experiences on using a lifter bore grooving tool. Does it help prevent any damages to mech. roller cams/needles ? Tool seems not to be overly expensive. Pro's con's ?

[Belgian1979]

Nobody ?

At risk of derision from the pros here:

A hacksaw blade in careful hands can groove lifter bores. Zero cost method to try and see if it works for you.

Ok, thanks, but it's not so much the cost of the tool I'm worried about. I would like to know if it would help lifters live on the street and therefor would be worth the effort and money and if it has any side-effects.

I have one and use it on flat tappet cam, which is what i think it was made for. Not sure how much it will help on a roller to lube the needle bearings, but I don't see how it could hurt.

I see no ill effects from doing this, does seem to help flat tappets.

Why not just pay a bit more and get the premium roller lifters with forced oiling.

A true "street roller" cam designed for street and marine endurance and typically runs with relatively modest spring pressures
Will not cause undue wear issues. (They are designed not to beat up the valve train)
Adding a simple Rev kit to a mechanical street roller will keep the rollers loaded thru full rotation of the cam lobe.
Adding a rev kit ( AFR's Hydra Rev) to a hyd rolller adds rpm capability and ensures top end power beyond 6500 rpm.
Much of it is in the cam lobe design.

Crane, Comp Isky, Lunati all have "Street Roller" cam designs and matching kits.
They make great power and live on the street.
Race cams are for race cars.

Well I had Mike alias camking grind me a cam. Don't know if it classifies as a street roller or pure race cam. Stated it was going to be used on the street.

Spring pressures are not overly big.

Revkit is already foreseen. The lifter came in the package. I thought they had the pressurized oiling but apparently not. In Europe it is not a sent back type of deal...

The groove will do little to nothing for a solid roller application
Wast of time in anything but a flat tappet & there I would use EDM with a solid, the groove with a hyd

You want the oil at the axle & squirting oil to the outside of a rotating object is not the most effective way to get it to the center

[hodge]

I'm currious to what block you are using and wanting to groove

[rustbucket79]

I believe he has a Bowtie block.

[Belgian1979]

Correct

[Belgian1979]

I know the grooving was mainly done to help flat tappet cams. However (and I'm no expert on this) I assume that squirting an additional amount of oil onto the cam and rollers, will find its way in the roller as well and therefor lubricate it.

If I'm not mistaken, it cannot hurt either, right ?

It's just an unneeded machining operation in your case and will do little or nothing. (that procedure is for flat tappet cams). Your just adding leakage for nothing.

Spend your money upgrading to pressure fed lifters.

Mike Jones knows how to make an endurance roller profile, you can be sure of that.

[hodge]

X2 don't groove, use pressure fed oiler to roller-lifters, the groove will put excesive oil to crank and lost oil volume for top end, for no benifit

[rookie]

I would think if you off set the groove and positioned it on the top side off the lifter it would put a stream of oil directly on the axle of the lifter, BTW, the tool is a little finicky but it does work.
