solid lifters

[Guillotine]

does anyone have experience of solid lifters?

my griff 500 is tapping AGAIN after the following.
new...
lifters (x2 sets)
rods
rocker assemblies (x2)
oil pump pressure check & strip
oil pressure valve
oil change (several) now 15/50 from 0/40.
oil pressure test - ok.
blown out oilways and clean sump pick up.

about to take it to bits again and am considering solid lifters with adjustable rods.

will check for cam end float, but the sound is definately lifter. tapping from centre/front of block.

ps its definately NOT exhaust gasket

steve heath are you there?... anyone!

[Guillotine]

yes, pre loads were set each time
yes, cam was checked.
may take the cam out totally this time to ENSURE its ok but was checked insitu and no real wear was seen.

wierd (and expensive) huh!

i should say that all work has been carried out at penninsula and they've gone out of their way to be friendly/helpfull.

just looking for fresh ideas

is it worth fitting solid lifters?

[Guillotine]

sounds good, thanks for the info

was it used in a race or road car?
where were improvements?
idle?
mid range?
acceleration?
overall?
richard and i will be doing the work next week and i like the sound of this (he did mention it)so if its not too expensive...

adjustment every 6-10k is ok as it would fit in with normal servicing/use

firstly i just want it quiet, as its fine otherwise.

cheers

jmorgan.
yeah, solid lifters are just that. no hydraulic mechanism - back to the old system of adjusting the tappets manually (adjustment in new rods so rockers remain)
danny,
yeah, i'd agree with you. i'd rather sort the problem, but its getting expensive and not a little annoying!
i'd like to go in and be sure the problem will be sorted this time. hence the solids.
atleast if i go that route the problem will be sorted! and if i end up with a better cam/performance, then i'll get something back for the money as well!!

here's hoping! don't know how much the cam is yet!

phil,
oil pickup has been checked and no drop in pressure has been seen at any time
glad you got yours sorted!

other info in the saga.

the noise appears to have moved this time.
previously it was difficult to pinpoint just where the tapping was coming from ie top rattle or lower rattle.
hence the changing of upper assemblies (both sides)
this time,however, the noise seems quite clearly from the lifters and definately from the front.
so maybe a duff one went in this time.

on new lifters, rods, tappets the car sounded lovely.
drove to nurberg... 6 laps... back home and sounds like a diesel!!!!!

by the way, the cars is a 500hc pre serp '94 with 40k on it

cheers

danny
will do. ta

[Guillotine]

not sure yet, will be doing it on monday.
i think its a question of shimming the rocker pedestals to obtain the correct spring pressure, but not sure...

was that your twin throttle plenum at penninsula/ if it was it looked interesting...very interesting.
if so, do you have the rest of the induction kit - is it worth it?
let you know how mine feels.
tell us how you get on.

[Guillotine]

ha!
just seen your thread on the griff site.
tim...new plenum...new about my cam...act!

sorry, bit slow there! must get to meet you at some point, i WILL be developing my car over the next few years! via penninsula / act, once i've got it sorted.

ofcourse you like the act induction gear! DOH!

took it to bruntingthorpe today with easytrack.
its difficult to assess - coming from a cam with 22.5mm on some lobes! (should be 24.5ish) BUT:-

the reving feels much easier with improved response from 2.5 - 3.5k. most of the high speed part of the circuit was done in 4th (i could do practically all of it in 4th!) ranging from 3 - 5.5k, with 5.5k held for some time, i would never have done that previously but the free reving seemed to WANT to hang in there.

would be interested in your dyno results, particularly in the mid range as the standard 500 power delivery seemed a bit gradual prior to this
