Motor problem, need help
Well basicaly after hearing a funky tick and grind coming from behind the front right wheel i decided to diagnose it. Took off the surpantine belt to run just the motor and guess what, all that noise was coming from the crank pulley and now i'm very upset with it.
I've come up with 2 reasonable answers to it
1- the rod pin thingy dingy (brendan told me about that)
2- crank shaft bearings
Soooooo, what do you guys think?

if i do need a rebuild, can i have some forged light weight parts please?

Re: Motor problem, need help (G60ING)
well it is only between 2-3k rpm and there is no squeeking @ all, there are a couple different types of rapid ticks happening (rpm depending). sometimes it sounds almost like the sound of a bad alternator bearing, or a bad waterpump. To be even more specific, the noise comes exactly from the crank and rear part of the motor by the crank pulley.

I'd pull the belts off the engine and try turning the waterpump pulley by hand. You'll know if its bad when you do this. I doubt there are problems with the crank's bearings but maybe you've spun a rod bearing.

Re: Motor problem, need help (RedFuFuG60)
Here are some pics of my worn rod bearings....
What do you mean by "it has no power !" ???????
that i'm sure it has nothing to do with worn rod bearings!!!!

Re: Motor problem, need help (RedFuFuG60)
I ran my car for 6 months with knocking rod bearings, including three trips on track days!
When I got in there rods 1 and 2 had already been treated to new bearings( date stamped on them) rod 3 had been inspected and put back and rod 4 was long gone.
I know that someone was in there because the ends of the bolts on 1,2 and 3 had been marked.
I had to reuse the bolts as I had no new ones. I thought that I would be the first to pull the sump and the Bentley says that it's ok to reuse the bolts once, hence the marks. Anyway there has been no bad noises since and that includes another trip to the track and a run on the rollers.
I have new bolts and nuts sat in my garage waiting for warmer/drier weather. I have a guy in the machine shop at work making a tool to press out the old bolts, so I won't break anything with a hammer.

My bearings looked a lot like Vedders, the ones nearest to the oil pump were in the worst condition, they were the oldest according to the date stamp.
There was no damage to my crank and the car has run with no trouble for 3 months since I changed the bearings. FINGERS CROSSED AND RABBIT FOOT IN POCKET

These engines can take some beating, so unless the knocking is making you wince, I'd just drive normally til you get the bearings done.

Re: Motor problem, need help (H100VW)
well I took off the oil pan last night, took appart the rod bearings, feel inspected the wrist pins and slapped it all back together a couple hours later. This is what I found:
a few metal shavings in the oil, nothing too siginificant. All rod bearings looked ok with just minor lines on them from normal wear to rods. wrist pins seemed to hold everything in place pretty tightly. Took a good look into the cylinder walls with attention to any piston slapping, and yet there was nothing, but perfect mirror surfaced walls. the only thing left uninspected was the crank bearings and that's because i did not have new bolts to replace the old ones, I know that those things stretch when they're on there so I didn't wanna risk it and put them back in.
Conclusion:
I'm confused, the noise is there and it's annoying, the internals of my motor are super duper clean and nothing is obvious which leads me to think that if there is a problem it's barely to any cignificance. Now i'm thinking about buying new crank bolts and checking that part of the motor too.
Any ideas anyone?
