Assuming valve springs are set up the same, spalling on the intake only suggests it's an issue of the larger forces involved due to the heavier intake valve. I doubt the heat treat or core is any different intake vs exhaust so we're back to an insufficient heat treat or material for the...
I'm with you. I've hand-packed the bearings on my flat trailer since I bought it used in 1986. Never had an issue with it. Now with my enclosed hauler, I've used the EZ-Lube method for the first greasing and will likely hand pack them when they're ready for the 2nd greasing. I figure I'll...
I've got EZ lube hubs on my enclosed car hauler trailer and just greased them for the 1st time at about 6800 miles. It took quite a bit of grease this 1st time as you're filling up the hub cavity when you do it. And these are 6000# axles so they have the bigger bearings and hubs. Roughly 1...
Just a guess but most tracks will (rightfully) insist on an overflow bottle. On a temporary basis, any type of old plastic bottle may suffice. That is IF tech even lifts the hood like they should.
Oh, and double throttle return springs are in EVERYBODY'S best interest!
I should have added that, like your car, my avatar has the fully adjustable SPC UCA's so doing this at home is quite the necessity to me. And by having the gauge magnetically attach to the hub as I noted in my post above, repeatable results were quite easy once I got the knack of how to adjust...
Most importantly, go over your safety checklist: wheel nuts torqued, suspension bolts tight, fire extinguisher in car, oil level full, etc, etc. Go get'm and have a blast!!
I have a Joe's Racing caster/camber gauge. The avatar has Weld ProStar wheels. All I have to do is remove the center caps then the dust caps and the gauge magnetically attaches to the hub without issue.
For turning plates, this hack uses heavy, thick garbage bags folded over multiple times...
Can't tell exactly if that damage is on the nose of the cam or the front or back side. From the pic, it looks like what we would call spalling which is due to excessive Hertz stresses from too much spring pressure for the material and/or incorrect or insufficiant heat treat. For example, iron...
I've had my car at 5 different tracks. Only 1 has ever done any meaningful tech inspection (little track in Michigan called Lapeer International Dragway - cudos to them!). All others (names withheld) have never even asked me to lift the hood!! So not even a simple check to insure at least...
I use an Optima red top in the avatar's trunk. For the disconnect, I use a rotary switch in the trunk latch key hole. I have a pull cable in the LH rear pass seat area to pop the trunk latch.
:poke:Dang John....picking on us little guys!! That 440 was built in 1990 and it's last race - yes the very last time it was run - was winning the Heavy ET bracket final at the old defunct Detroit Dragway!. That was back in 1993!! Hasn't been started since but may see some love in the next 12...
Yes, and the REAL problem is nobody runs all the tests to determine what these old engines really require given all of the mods done to them by each of us!
Pretty darn close on insurance - both home and car. We pay a bit less for home (includes screened pool and detached garage) and will pay a bit more for car (& truck). But I'm in Citrus County - 30 miles s/w of Ocala, 8 miles from the Gulf.
I don't think I necessarily need a colder plug but, if I want to add some spark, it should not hurt it either.
I worked for an OEM on engines my whole life. Always target to get the coldest plug that doesn't foul under the worst conditions, be it granny starts and drives or repeated cold...
