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.

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.

      All trim back in wired running driving. Few things to follow up on but not far off the return to the road. att.6HN4wP38LTIOISkhA8eACoBFqzfgQMahZPLA8ut0pqE.mp4 att.w2q0ux2PGuqgQTj2Os13cNHQtqcSEcCAhD_CAXy_IQM.mp4

      Mistakes were made, my R34 Story

      By GTSBoy · Posted

      The trouble with phone apps is that they really do not know the sensitivity of the mic on each specific phone, whether there is some sort of cover or skin that can change that, etc etc. So the readings off them are not calibrated. You certainly couldn't be sure that you were even within 3 dB. I have the same app on two (actually more than that) different phones/tablets and the readings in the same room at the same time are never the same. I don't mind the apps - they are as useful as a dyno - if you're testing for delta from thing1 to thing2. But not to try to generate some sort of absolute value.

      I'm gonna use the "Sound Meter" app from the Google Play Store and as close as I can bother to these procedures: 4. TEST METHOD FOR ALL VEHICLES EXCEPT PRE ADR83 IN-SERVICE GOODS VEHICLES AND OMNIBUSES 4.1 Microphone position 4.1.1 The microphone shall be directed towards the orifice of the exhaust outlet and shall be supported by a tripod or similar device not providing excessive acoustic reflection. The general requirements for positioning microphones are shown in the Appendix. 4.1.2 The nominal axis of maximum sensitivity of the microphone shall be substantially parallel to the test site surface and shall make an angle of 45 degrees ±10 degrees with the principal direction of gas flow from the exhaust. 4.1.3 In selecting the 45 degree alignment from the outlet of a motor vehicle fitted with two or more outlets, only the angle resulting in the microphone being farthest from any other outlet must be used. National Stationary Exhaust Noise Test Procedures for In-Service Motor Vehicles Page 3 4.1.4 The height of the microphone above the test site surface shall be equal to that of the orifice of the exhaust outlet ±25mm but shall not be less than 200mm above the test site surface. 4.1.5 The distance of the microphone from the exhaust outlet orifice shall be 500mm±25mm. 4.1.6 [Relates to vertical exhaust outlets] 4.1.7 For vehicles fitted with one exhaust outlet the microphone shall be placed so that the greatest possible distance is achieved between it and the vehicle. 4.1.8 [Relates to multi exhaust outlets] 4.1.9 [Relates to multi exhaust outlets] TLDR: 200mm off ground 45 degree angle relative to exhaust flow 500mm from tailpipe exit. (I probably won't use a tripod) Here's a photo, cause I read the instructions wrong myself.

      No ABS, no TCS, no airbags, no cruise control, no lane departure assist, no emergency brake assist, no orange lights in the mirrors (continuously annoying me in multi-lane traffic), no stupid rear view camera. I am the one responsible for where my car goes and how it does it.
