Can you tell if the knock is in the top part of the motor or the bottom ? If it is in the top, you could have a lobe on the camshaft or lifter that is wiped out. The first 30 minutes of running a new engine is the most critical time. This happens every now and then when breaking in a new engine. Normally it is recommended that you use a special additive or a special motor oil that is high in zinc during the break in process to eliminate this problem. Did they send you any special instructions for breaking the engine in ?

If the knock is in the bottom of the motor it very likely is a rod bearing or possibly a main bearing. This type of issue will only get worse and if left unattended will most certainly result in major engine failure. One of the first things I would do is drain the oil and get a strainer (paint strainer will work) and strain the oil and see if you notice any bright silver or copper particles in the oil and filter. If you notice these particles you can be pretty sure that you have wiped out a main or rod bearing. You will also normally notice a gradual loss in oil pressure as the clearances between the crank and bearings begin to steadily get larger.

Regardless of the problem; I would definitely demand that they send me another engine. No one should have to go through such a run around such as this after making a new purchase that is under warranty.

If it were me, I would have determined where the knock noise was coming from - its either the valve train, possibly the fuel pump rod that runs off the camshaft, or the bottom end - crankshaft mains or rod bearings..

One question - did you guys spin the distributor gear up with a drill to pressurize the oil pump first, before you started it ??? Verify the oil pressure with a manual (true oil pressure gauge) gauge before you started it ?

Any pushrods come out bent after you took the valve covers off and looked around there???

Ive seen and built a few small blocks and never had this issue at start up but I also went through and set the rockers to the prescribed nbr of turns on the lock nut, and then went back through after it fired up, ran and shut it off, and checked for any a little too loose...

Perhaps there were a few lifters that were not pressurized with oil from the pushrod tubes for awhile???

Next, would be a little concerned about what the camshaft lobes might be looking like..
Hopefully, they put a good camshaft assembly lube on all the lobes and lubed up the camshaft bearings, etc...

Geez, this cant be so hard to do!!! Sorry this had to happen to you guys...

The latest "whack a mole" thing they think it might be is the cam, or a lifter or.........

This is really bugging me since the person I sent the pm to on the other forum has been staring at the pm and the thread for over 2.5 hours. and nothing

I thought my pm was strong, pointed but reasonable.

I`m sittin here losing patience.

As far as oil is concerned, it was sent with "break in oil" I believe 20-50 rotella, oil/filter changed at specified interval with I believe 5/30 (again specified)

[Ronkh]

Hmmmmmm

Mr engine guy, just registered here.

Anxiously awaiting his response

Ron, are these engines actually blueprinted or is that just the companies name? If this engine is papered, dial indicators and mic`s could certainly be used to back up anything your mechanic finds. It should all be there on paper right down to the oil pump.

Dunno Mark,

He just signed up here, so mebbe he will answer, hopefully he will decide that this is serious, and replace the engine. You remember my Audi fiasco.

[RaysWay]

Good luck Ron I feel your pain. I had a similar situation happen with a motorcycle engine a few years ago. Luckily they resolved it. Good luck hope to see this turn out on a positive note.

[GearHead_1]

Yes` I remember. Hopefully this will be resolved more easily.

I was just rereading this and the FBody forum posts. Is this a stroker? Rods touching the block make loud knocks, bearings could blue print fine. Wrist pins will also knock. Valve train noises are often spoken of as ticks and clicks. Knocks are more commonly bottom end stuff, even something like a loose flywheel.

This. If before initial start up the oil pump wasn`t primed, and the motor was fired dry, that would almost guarantee a spun bearing somewhere in the rotating assembly. Also, if it wasn`t properly primed, they may fault you for improperly firing the engine while it was dry.

[Ronkh]

I don`t think it`s a stroker.

As far as I know, they (blueprint) tested the engine before sending it out. I may be wrong, but I think they did.

They said there is something wrong with the engine not disputed, but they just say try this, try that, and we`ll send ya some parts and that them.

The guy from blueprint had that pm before 3pm, then I linked a pm to him about this thread, he signs up here, sits for a long time and nuttin.

It`s time for them to take care of this or a case of preparation h won`t take care of this hemorrhoid. I`m sure he will be having a great weekend though.

getting more and more annoyed

This really sux mate , hope that company will resolve their issues .

Who s gonna pay again for all these ! The consumer as usual .

So far my kid has paid.

The company better step up, or the consumers will go elsewhere and they won`t have to worry about it much longer

[sprocketser]

True man , I was thinking of buying one engine from them in a later day , but I ll forget them from now on ! Thanx for sharing .
