new built 1950cc engine with gt3076r

[Scholzey]

We are confident it is not through the sleves, or at least not below the rings, as the oil looks fine. We will find out on Monday weather the re torque works.

[tinkerbell]

also - did the compression test reveal anything?

[Scholzey]

When we checked for pressure leaking into cooling system, we did leakdown on number 2 cylinder which came out to about 3 percent.

Before the head gets torqued down on Monday they will do leakdown on all cylinders, then torque down, then check for coolant system getting cylinder pressure again, maybe leakdown again.

But not sure if 2nd leak down will change from torque down. The mechanic said the leakdown from the test on cylinder 2 was unheard of, or basically perfect.. So he said the bottom end was still healthy.

One other thing, I drove like this for 5000km and I think he said the piston looked pitted, so hoPefully the coating hasn't been blasted off from the water/ detonation from water.

[Scholzey]

Leakdown in all four cylinders was 4,4,4,3% which is really good.

Re torques the head studs by pulling them to 70 ft lbs from where they were. One of the most outside nuts moved about 20 degrees. All others didn't move.

Pressurised the radiator. Put the camera down the hole and saw some water re appear. Flow is really slow so it's hard to pin point, but it creates a a drop on the exhaust side quench pad. We didn't actually see a drop rolling down the sleve but the other day when the engine was hot, we saw a drip roll down the sleeve. So we think it's a cracked head, or pinched o ring on the gasket somehow..

So I guess from here we have to take the head off, and I'll probably send it back to the us.. But I'll hear back from the engine builder before we take the head off..

Not good! Not the type of thing you want to see from your freshly built motor

Hope everything works out for you man!

What part do you plan sending back to the US?

[Scholzey]

The head.

He wants me to pull the head off and check if the sleeves are flush with the deck. He said he is preparing another head and gasket for me now so when we take off the head and see that it is a head or gasket problem, then I can just bolt a new one on. But if the sleeve has sunk, which I would think is very hard to do on a dart block then I guess there is only one thing to do. Take the engine out and send that back as well.

We will find out tomorrow about the sleeves.

I'll keep you's updated.

The way endyn is handling this makes me happy I chose them. Just unfortunate what has happened.

Glad to see they're looking after you mate. Customer service is the most important thing any company can offer IMO...

[Scholzey]

head came off today. cylinder 2 sleeve 6 thou below level of deck..

[STOCK]

omg, i feel your pain....

[Scholzey]

Had a few emails,

He said that I can send the whole motor back and they will fix/replace and pay for shipping both ways.

So my costs will still have been

Investigate
Remove head
Remove engine
Put head on
Mount on create
Unmount from create
Re attach fittings to head/ block
Reinstall engine
Retune to be safe.

Another few thousand down the drain. But not as bad as it could have been if the builder wasn't so helpful in resolving this.

I guess.. Watch this space, another engine will be on it's way soon.

[Slaz]

Consider yourself very lucky they have been willing to do that.

I had a similar issue with a set of sleeve's that went oval on me, all i was offered was for them to remove and replace them, no shipping costs or anything.....

Hope all goes well 2nd time round! = )
