R35 Engine Replacement Problem

[Dominic]

After blowing the engine of the R35 into 4,823,163 pieces (Yes I counted) I decided to get my local mechanic to fit the engine rather than doing the sensible thing and send it to Martin at Willal.

WELL on opening up the lines etc there are pieces of engine in the oil cooler, in the filter in all the oil lines we even found a gudgeon pin in the throttle body.

We are going to flush everything out but how can we be sure that there is no shrapnel left in the circulatory system of the car.

FARK!!! thats a Huge Let go!

There's probably no easy way to do that, other than manually disassembling all connections and peering into / flushing them. Assuming fluid can sufficiently pass through the circulatory systems when you flush them, they should be safe. Worst case scenario something dislodges down the track and blocks up the works, but shouldn't cause instantaneous catastrophic damage unlike things trapped in the intake.

The intake and breather side of things is, at the least, what I'd be pulling apart piece by piece and either replacing or making sure they are free of shrapnel. Anything that can make its way into the throttle body etc.

Metal detector / stud finder might be of use?

replace the oil cooler cores. too many fine passages in there and just too big a risk to flush and hope for the best after a catastrophic blow up. remove and flush all the oil system lines and even the cooling system (un-usual for stuff to get into the coolant circuit though). as far as inlet goes I'm sure head has been replaced/rebuilt so just need to remove the inlet and exhaust manifolds and clean them out properly.

Thanks guys,

Im going to take a billion photos of the engine when out and cleaned and then turn it into a Top Gear style Coffee table (If my wife lets me keep it in the house)

Thanks guys for the oil cooler advice.

I guess I'll be the first to ask....

how did it happen?

Gudgeon pin in the throttle body - how the hell do you manage that

F....d if I know!

Just driving through turn 9 (The one after Corporate Hill) at Eastern Creek when I heard a huge bang.

I thought it was a tyre blow out until the car came to a slow halt leaving bits and pieces of car across 800 metres of track

pic's please

If you are concerned even after flushing and pulling stuff apart consider mesh filters in various supply lines to the engine (coolant/oil etc etc) after putting back together. Similar to the ones used in dry sump setups.

warranty? or was it mod'd?

[Snowman]

It was a JDM race import.

SURE = 100%. You cannot be sure. Apart from replacing the entire system.

But you can be reasonably sure. Flush lines and components with solvents, look at the outflow.

Throw stuff that has small gaps (e.g. oil coolers), hope for the best.

Afaik the stock oil cooler is about 7k from nissan aus.

Seven thousand for an oil cooler! Thats f**king insane...

My wallet hurts just reading about a VR38 dying, hell I was sad when my RB20 gave up the ghost.

[boiracer]

what ever happened to this?? where are the awesome photos of the carnage??

[EuroDB]

This was refreshing. I wished I could read every post, but i have to go back to work now... But I'll return.
