Urgent Help Needed!

[mickr33couple]

Hi all,

Got my engine rebuilt forged internals etc standard head just with 256 cams

Cranked the engine to build oil pressure, cranked it for like 5secs got 80psi pressure, started the car up and straight away lifters started tapping off its head,

Before anyone says take it to engine builder, I will on Monday when he open but been weekend Ill like to try work out what's wrong with it,

Nitto oil pump, still running VCt, blocked middle, 1.5m rear restritors,

Only thing I'm thinking is engine builder didnt do cleanances right? But I highly doubt it,

Bad lifters? How can I tell?

[kitto]

Solid or hydraulic lifters?

Hydraulic lifters will tick for ages until oil is forced into them.

[mickr33couple]

Hydraulic lifters sorry,

Thought that as well, we had it at normal temps, (half way) took it just for short drive under 3000rpms and still ticking,

It seems to rev slow like it revs and the come down revs is slightly sorry

[mickr33couple]

Maybe havnt had it running for long enough to force the oil in them

It's prob had 10mins running time just didnt wanna wreck anything

[NYTSKY]

Scary noise to hear on a new engine but it is perfectly normal if the lifters have been out and drained.

[mickr33couple]

I was so nervous to start it as I have had so many issues in regards to work that was done on it, I didn't wanna start it... But just from

How loud they are and all the time doing it, I didn't wanna risk driving it and causing more damage, but yes they have been out of the motor for about 7months dry,

If its a fresh build you shouldn't be idling it or taking it on a light/brief drive.

You should be seating the rings or you'll stuff the build entirely. Tow it to the builder/dyno Monday and don't keep starting it now. All you should do on a fresh build is let it run for a couple mins just so you find any potential water/oil/air leaks etc.

[NYTSKY]

As above.

Get the car to your tuner so they can run the motor in, refresh oil and filter then take it for a belt. Any issues should show within the first couple of hundred kms if any.

[mickr33couple]

Motor never idled, I was told by the engine builder to do 1 hour of driving under low boost drain oil then same again, m

Rang another place they told me they put it on dyno and go for gold on it

[mickr33couple]

Ill deff won't start it anymore and get it tow to a dyno for them to run it in hopefully they will do it with it tapping off its head

[mickr33couple]

Also using penrite running in oil which is 15-40w is this too thick?

[abr33]

Not too thick. With the hydraulic lifters, once cars been running for 5, shut it off and next day it'll be silent they self bleed over a day

[mickr33couple]

yeah fair things i wanna check like cam cover just to make sure its not hitting it was late yesterday arvo 5pm and once i heard the noise i didnt want anything to do with it for the day was a let down she packed up closed the shop lol

[mickr33couple]

Got the car on the dyno for its run in.... Lasted 30mins resulting in seized cams

[StevenCJR31]

sounds like it was more than just noisy lifters then!

[Risking]

Was the previous engine blow up a spun bearing by any chance??

It's so common this happens when a small bearing particle blocks the head oil feed from the previous blow up and you end up with stuff all oil to the head.

It's bloody hard to have the galleries cleaned out perfectly unless the original restrictors are removed.

A lot of engines I've seen built by various Motorsport teams like the supercars have external feeds to the cylinder head with inline filters to prevent this happening.

[mickr33couple]

Hole bottom end was destroyed in the old motor, started again with block and crank, only think that didnt change was the head, but engine builder knew what happen with old motor and I told him to wash the head and he said he would do that,

Only thing that was used from the spun bearing motor was the head, lifters and cams? Could these of been f**ked from the old motor? I asked the engine builder to check everything to make sure it was all good to go back in

[abr33]

Thats too sus, there has been something missed dude.

[mickr33couple]

Would like to know what, coz this is pissing me off. Like to hear what the engine builder has to say tomorrow

[portaz]

Any news?
