not if they're chrome/polished stainless mate, they burn into the surface somehow and are a fu**er to get off. and with these being white we don't want burnt stains on them so won't be taking any chances.Quote:

Excellent work, i wouldn't have the patience to do that for temporary use, but we know how much you like making headers!
cam bed in completed, we just have to tweak the timing and carb today before a test drive. :thumbs_up_smiley:
neil.
2 steps forward and 1 step back.... ggrrrrrrrrr :mad:. today it started fine, the idle mixture screws needed almost 2 turns out to get a decent idle. the timing was at it's best so didn't need changing. then a quick blip of the throttle and it started tapping followed quickly by loud popping through the carb. we removed the rocker covers and spun it over checking for correct valve opening which seemed good 'til we saw one of the exhaust valves was barely opening, doh! once the rockers, pushrods and inlet were removed we tried to get the offending lifter out which only wanted to come so far. with some levering from underneath and wiggling with pliers it finally came out. the bottom is worn badly hence the tight removal but worse the cam lobe is fubared too.
it's no good as it is so we just ordered a (one up from stock) 428 cobra jet cam and lifters from rock auto which should be here tuesday next week. here we go again :whistle:
neil.
ps yes we used high zinc oil and cam break in additive too.
Bad luck that Neil [emoji3525] Lets hope Rockauto do there stuff over the weekend [emoji1303]

let's hope so. it's the first flat tappet cam failure i've ever had in 40 years so i shouldn't complain. still i will as it's bl00dy annoying!!
neil.
Where where the cam and lifters from Neil?
cam was a 90's crane fireball grind and lifters were melling Tom.
neil.
Was wondering if you stand anywhere with warranty ect if this sort of thing happens, I suppose there is no way to prove anything.
I guess roller has its plus sided but comes at a
cost too.
i suspect the only way you'd get a claim would be if you had a continuous video of adding the fluids and the full cam break in procedure. other than that all you'd get is 'you did something wrong'. i assume the camshaft from the 90's may well be out of warranty now though :lol:
neil.
that was quick as usual from rock auto, the cam, lifters, lube and gaskets arrived today (3-4 days early). :thumbs_up_smiley:
neil.
That's some service Neil [emoji106] good luck with the refit mate.Quote:

reassembly time tomorrow.... again, lol.
the flushing/pumping went like this. pump up bottle (set on 'jet') filled with petrol to clean the cam bearings front to back followed by drain the oil and filter. drain and refit the filter and add a gallon of diesel through the lifter valley. hand prime via the oil pump driveshaft til we had diesel gushing from all the cam bearings followed again by draining the sump and filter. lastly pour 1/2 gallon or auto trans fluid/oil in through the lifter valley and hand prime again. drain yet again followed by pouring a couple of litres of clean engine oil down the valley while the sump plug was still out to clear most all of the tranny fluid out.
so it's as good as it's going to get without a full tear down and rebuild.
hopefully we'll be able to get it back together and have a 'take 2' moment a week to the day after the 'take 1' failure.
fingers crossed it goes well and all 16 lifters keep their shape as they should've done last week.
neil.
we're nearly there, it's too late for a noisy cam bed in procedure now (7.30pm) so it'll be tomorrow afternoon when ash' finishes work. the new 19" wide blade flex fan arrived from summit racing today, she's a biggun. the back edge of the blades just touch the damper/crank pulley so needs spacing forward a couple of mm to clear. easiest way to do that was to super glue 2 crash repair washers over each bolt hole on the front of the water pump pulley. that'll go on tomorrow along with the radiator and fanbelt ready for the fire up. we may 'hang' a 14" spal leccy fan i have here down the front of the rad' with temporary wiring and switch to a slave battery to boost airflow if needed during the run in. fingers crossed all goes well this time.
oh, the destructions with the melling cam kit say run the engine at 1500-2000 rpm for 20 minutes. most others say 2-2500 rpm, maybe they're being careful what with how common failures are these days. who knows but we'll do as they say.
neil.
We used to trickle some cold water over the radiator to help keep coolant temps down while running in worked a treat
