Help needed with Perkins 404C-22 non turbo
 

Hi,
I have a Perkins 404C-22 non turbo in my RC 50 ASV Posi track loader.
The problem started when I tipped the machine forward (overbalanced).
I have a bad noise coming from front of engine (I Think).
The engine will run at idle, but if rpm are up at operating rpm engine will only run for a short time and stops like it has seized and won't even turnover, but will restart after leaving it for a bit.
I took tappet cover off and ran engine, after short time white smoke starts to come up from pushrods.
The higher the rpm the more smoke and then after a short time at the higher rpm the engine stops.
Does anyone have any idea's.

Thanks Steve

Smoke coming from push rods could be blow by, that is normal, can diagnose from behind a computer to tell if yours is under normal conditions.
You say that you just tipped it over, describe that more in detail, did the front of equipment get damaged, was something bent?

You also say seized, not sure I can understand that one as well, are you saying the motor will not turn over anymore and after it sits for awhile it will or will your motor turn over but will not fire?
Is there any leaks
What is the noise that you hear sound like?
Have to clear these things up before we can go any further on this

Thanks for the reply.
I tipped the machine forward to approx 75 deg onto the bucket, I was able to use bucket to level machine back onto tracks.
There is no damage to anything in front of machine.
The motor is in the rear of machine.
The engine will run at idle, but if rpm are increased the engine will lock up, similar to hydro lock.
When it has locked up, I have removed injectors so there is 0 compression and it will turn over after a few hits of the starter it will turnover.
Once injectors are reinstalled engine will start.
I was wondering if I may have damaged something due to oil not getting picked up when machine was at 75deg.
Regards
Steve
