R35 Engine Replacement Problem

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.

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?

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

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.

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.

Cheers,

      Well I had 2 choices from then on. I either had to (reluctantly) move it on to another potential buyer and take the loss on the chin. Or I stick with it and turn it into a restoration project. I chose the latter. Project Snowstorm began! The frp body kit was the first thing to go. Turns out the original colour used to be silver. The Neo and gearbox were removed, along with the prop and exhaust system before it took a trip to the bodyshop, where I wouldn’t see it again for quite some time due to the pandemic hitting very soon after they took it away. Eventually, progress began and damage assessments made. Even the front chassis leg was in pretty bad shape!     Then the chopping commenced. For these guys it was just usual routine, to me it looked absolutely terrifying!   More to follow as I’m struggling to focus on my screen at 12:45 am!!!

      That's the most absurd thing I've ever heard. I would go cut bellhousing over that monstrosity of a flywheel all day, every day. It puts a lot more mass further from the last main bearing. I've had nothing but problems with Collins in the past and refuse to ever buy their products again. I would not trust anything they tell you. He's playing his salesman card.  I'm currently at 640whp on a mustang dyno (~770bhp) with the intentions of running E85 and a lot more power this upcoming spring. Cheers,

      Nah, it's not the reduced knock margin. It is a direct mechanical effect of having to initiate the combustion earlier, while the piston is still rising, which starts to exert combustion pressure on the rising piston earlier, making the rest of the engine work harder to finish driving the piston up to TDC where the combustion pressure stops being a negative and starts being a positive. Your modern engine that only needs ~10° to make MBT doesn't waste the other 10 or so degrees of crank rotation. That's almost all of it. The difference in knock margin might go either way. Remember that modern engines to which you are currently comparing the long tractor engine (the RB) are now running super high compression, direct injection, tricky cam control and maybe even cylinder pressure sensors. You're not comparing apples with other fruit. It's apples and sea weed, or some other evolutionarily primitive vegetation. And remember, squish only really comes into play at the very end of the stroke. It certainly does good things, but it is not the biggest contributor to what's going on. It is quite possibly much less important in 4 valve head than 2 valvers also, because there is so much less squish available to a 4 valve anyway.

      Food for thought, a longer stroke motor would need less ignition timing vs. a shorter stroke motor requiring more ignition timing.

      Thanks Duncan, HART is only 10 mins from me (I did my bike license there), it'd be awesome if it ran these types of things.  Sutton Road does look good and they take fewer cars than SMSP which is good.  Surely you have enough land to lay a few million tonnes of concrete and some sprinklers D?
