like roadkill when they cool they're cr4p down going from car wash to car wash, lol. unfortunately it's in my garage so i can't do that mate. he had a flex fan the same as this new one before and it ran at half on the gauge even when he was hot lapping at manston with the car idling the whole time in the fire up road. the elctric fan is a just in case where it's in my garage with no airflow to speak of.

**mygasser** · 02-08-25, 03:52 PM

it's almost groundhog day today. it runs cooler with the bigger fan, but.... and it's a big but it's done the cam/lifters AGAIN!!!!

ashley's delighted..... not. i'm not happy either. the plan for now is pull the engine, swap the poncy bits back onto my fe and bolt that in. at least he'll be back on the road again. he said he wishes we'd left it alone now as it was ok if a little slower than he wanted. i had to say i told you so i'm afraid, i couldn't help myself

good job my glass is half full is all i can say really.

Oh that's not good news Niel sorry to hear that.

That’s interesting. Did it do the same lobe or another? There’s an issue in there! Lack of oil or something pushing hard where it shouldn’t be? Valve geo out? Too much spring pressure? Can’t be a cam problem twice in a row!

**jsf55** · 03-08-25, 10:33 AM

I'd be looking at a valve problem for that too happen twice, lifters changed and how about pushrods for length? do they have the oil holes running up them ?

**Happydaze** · 03-08-25, 11:59 AM

Some guys have all the luck! Obviously not you though. What a bummer.

Probably not the case here but some valves (dont know which) dont jive well with some guides (again, dont know which)! Something like differential expansion resulting in there becoming a temporary seizure. I know its caused the best in the biz problems on a buddy's engine.

it's happened to different valves this time. the pushrods are solid so no oil in them. the valves are in their same places they always were. i know what the problem's called but can't post it here or the AI will edit the words, lol.

**tom.marg** · 03-08-25, 01:51 PM

Valves might be in the same place as before but you have a different spring?
Valve seat pressure too high for the cam?
Or lack of oil to the cam, not sure what AI can do with that lol

428 cobra jet springs to go with the 428 cobra jet cam kit Tom so should've been fine together. as for oil to the cam', the bearings had plenty as i could see during the flush. and as for oil splash to lube the cam lobes all anyone can do is follow the instructions as to what revs the engine should be at for the specified period during bed in.

Did you use cam lube ?

I know what you are saying about the valve springs but isn’t it worth a check unless you are confindent on the cause?
Are you thinking that the RPM isn’t high enough from the instruction?

revs were 1800rpm or thereabouts so near the upper limit of what they said. we also varied the revs slightly lower and higher during the run so everything you're supposed to do. the only common denominator in both cases was melling brand lifters. but even that's not a definate smoking gun as many name brands are known to fail in the last 10-15+ years. we must've just been lucky in the past. a mate's just run in a small chevy i built (with melling cam/lifters too) and it's fine as well as an fe ford like this one and that's fine too. it's infuriating.

It would be good to know why it?s happened twice for sure!

**jsf55** · 03-08-25, 09:40 PM

I think i've read so many of your posts i probably slipped up

we'll definately look into it when there's more time mate. there's so much now waiting to be done we don't really have time for the engine swap but needs must so.

and on that basis the cresta's off to a new home tomorrow at a mate's house. other than buying the windscreens and rubbers, some inner and outer handles and connecting the steering column to the steering box it's as i got it. he's got all the running gear from a 383 cu in jensen interceptor so it'll be fun if he gets it done for sure.
neil.

**mygasser** · 09-08-25, 12:11 PM

firstly the cresta's gone now.
ok, yesterday we had a good day on the zephyr. all the engine's ancillaries are off and we're just left with torque converter and bellhousing bolts holding the engine in. the flip front's ready to lift off so we can get the crane in, so early next week we can get on with the swap.
next job after that's done is not car related other than the garage will become a wood workshop, lol. we need to get the roof replaced on my conservatory as i't had bandaid over bandaid over the last few winters. it's getting a proper insulated roof with fibreglass skin and a jumbo 1.2m x 1,5m triple glazed window/rooflight which should brighten the back of the house inside a fair bit. what was the dining room has always been a bit dull since we put up the conservatory hence the change to a 'real' roof with the glass panel.
i bought the timber, window and fibreglass roof kit a while ago now so it's time to use it finally.
neil.

**jsf55** · 10-08-25, 08:56 PM

We didn't do the roof window as enough light comes in ours but the insulated roof will be great ...back on topic ..good luck with the pull out !!
