Damn. He's going to wait for the fall season to start so maybe sometime in October? It's funny if you watch the tele.. Lester
It's been soooo long now do we have to wait until you replace all the hoses, belts and fluids. 😜
… then he's going to want the engine bay freshened, and there's the Lotus roundup to attend, regional flooding, global cooling/warming, sunspots, and … ;-)
Oh bloody hell now I'm getting impatient..........with myself. Ok as long as I don't get run over by a steam roller in a 2mph traffic collision, then I'm doing it tonight, because I need to put this right and get using Kato the Ferrari again. Will be in touch tonight..... Catch you later chaps!
Hi Guys, got to help out a friend today. Nearly there now....gonna run it up tonight.... If it works I'll run it for 2000 miles and then recheck the followers. Then I have to decide whether I replace all of them with new ones or just 'hone' the other side and call it a day at that. Like I said before all the recon followers are in spec so no real reason to change them. Anyway I will report back later. Cheers, Bell.
Hi Bell, Just wanted to let you know that I too have joined the vigil awaiting news. I have been watching all your Helidoctor posts on youtube as well as this thread and have to say that all this is compulsive viewing.......you should get Cameron to make a movie. Hats off to you mate, your persistence and ingenuity is inspiring Cheers,
I might be going out a little too far on a limb ... but as much as I would hope it was, I don`t think the follower was the culprit waiting for the final solution of a problem that - so far - has never been documented
....Really Boody Trying My Patience Now!!!!!!!!!!!!!!!!!!! Yes the F******* noise is still there which means it's the valve in the guide.. So now what? Take the damn head off? If the valve hangs up in the guide then the piston may well come up and smash it into the head.... ..Let it be so I say. Summer is moving on time to drop the Ferrari and focus on something else, or just use the damn thing till it goes bang! Sorry Guys. Thanks for watching anyway.
"Yes the F******* noise is still there which means it's the valve in the guide.." If that's the case, and the noise is caused by the valve/guide interference, that would mean either that no oil at all is getting to that valve/guide which seems almost impossible or that the valve stem had been bent slightly. A bent stem could cause the interference/noise. Had there been any cam belt timing changes/adjustments/failures prior to the noise appearing?
Before you pull the head Remove spark plug. Feed some nylon string in spark plug hole. Bring piston to TDC, remove cam. Now you can make a tool to push spring retainer down and remove keepers. Remove spring. Inspect spring, seal, feel if valve spins, rocks sticks ect. If spring or seal seem suspect,replace and retest. If not THEN pull the head. I'd sure hate for you to pull the head for just a spring or seal.
Very sorry to hear this news. Also, did anyone else notice in Video part 3 at 2:50 while cranking there was no squeak. I think while testing the oil system but cam shaft was still in. If so then I think we are back at Crowndog's wind. LOL. Or did I miss something?
Hi Bell... You said have checked the spark plug torque but have you checked the integrity of the seal made between plug and head ? I am thinking that one of the mating surfaces may be compromised such that it is OK when cold but when warm the gap may be bigger ? It could also be that the nice rubber sealing ring of the compression tester provided a better seal and so masked the problem when u did the test. Either try another plug or fill the plug well with enough fuel to just cover all of the seal to see if the fuel leaks in or bubbles out under cranking. I realise that this sounds a bit simplistic but will only take seconds to check. I have followed this saga from the start and have just read back the whole thread and watched the video's and this is just something that occurred to me to check in the face of all the comments about the spark plug and everyone's reluctance to accept the problem being the valve bucket/guide . With you all the way mate...
Damn. But look on the bright side.. well for the rest of us anyway, it means that we aren't going to be pulling out all of our buckets and honing them. And now you have hours of fun ahead of you as you lose your hair and your blood pressure rises while you ponder the source of this noise in your sleep. Or you put dino oil back in it.. Thanks for all the diagnostics Bell! Lester
Well, at least something is eliminated. I'd be tempted to change the oil to mineral (the term dino oil always confuses me when discussing Ferrari). I guess you'd still have a nagging wonder about the cause and whether non-synthetic is simply hiding it. But it's an easy thing to do at this stage.
It would be tempting to run the engine with some TCW3 two stroke oil in the fuel 1:200. It's quick and easy. The added lubricity should help indicate if the valve guide/stem is the culprit. Good luck
Right now Guys I'm going to mask it with new oil and hope the engine doesn't go bang. Then when winter comes I'll do what Jessup suggested, good call by the way Jessup. I'm really reluctant to pull the head because I know what a pig they can be and I don't want an engine out situation as I don't have the time to get into that fight now. Just to remind you that the noise only occurs under Hot cranking with plugs in or out, makes no odds. Drove the car hard all weekend runs perfect pulls like a train, lovely powerslides out of corners etc, But still the noise persists under cranking only. Engine is smooth strong and quiet. All the best, Bell.
Conventional, as to grade.. that depends on temps encountered. Sae papers cover that well. For moderate climate a 10w30 is good, hot desert a 20w50... just make sure it has enough zinc.
