Engine Internals (pics!) Basic Questions

[rtune]

This isn't really quite the right forum for this question.

Pictured is the bottom (sump removed) of an N1 block with R34 crank, when last in motion, it had no oil pressure.

how it got that way is an interesting story I can type if anyone is curious. I've posted months ago on it, but basically

it involved getting ones timing belt changed at a "tuning shop" in sydney.

My questions are the following..

* see the shiny triangles ground off the crank, what are they?

* see the oil pump cog, and snout? the snout is damaged and there is molten and solidified metal blobs in the area. The stock damper has a crack in its inner most sleeve as well, I believe that perhaps this whole thing will be difficult to remove (I'd like to look inside this pump to see the undoubtedly fractured gear) How do I remove it?

* the bores are perfect, the piston tops perfect, where will I see bearing damage (for my own curiosity)? or where to look for any other damage? remove any pair of bolts pictured and look at the crank or the bearing sleeves?

* how do you turn the crank when the block is like this on a stand or whatever

* how do I keep this in good shape if I want to wait a while. do I clean off the oil and dry out the water jacket somehow?

I said they were basic questions!

ultimately I'd be sending this away to get refreshed, but I'm kind of interested in doing some of it myself.

Anyone got a brief description of what I would do?

for example: remove oil pump and free up crank, remove crank and send it away to get checked or re-machined, Buy new pump & bearings, and re-assemble and torque the bolts correctly and with the correct tools.

Download a copy of the workshop manual for starters, where are you located?

[Gerg_R31]

the triangles you mention inthe first picture have been machined, either for clearance or balancing reasons

the 2nd and 3rd picture shows the snout has been chewed up, repair to cost of a new/2nd hand crank, well id sugest to buy a new or 2nd hand crank

turn while on engine stand use a socket (usually 27mm) on the bolt that holds the harmonic balancer onto the snout, only turn clockwise

[STATUS]

crank is throw away. Look for a replacement but in all honesty i have bought 6 2nd cRB26 ranks over the years and all but 2 were no good.

do not clean off oil if u plan on storing it for awhile. oil will prevent corrosion.

crank is rooted, get another one

take off the two nuts at the end of each conrod, pull the cap off and look at the bearings. make sure u dont mix up nuts or the conrod caps between one another. and note the way they come off becoz they only go back on one way.

im guessing they didnt do a good job with the timing belt. what workshop was it?>
