1. seeking clarification as to which cylinders are MORE prone to scoring on the m278 engine? 1&4? 1&5? all of them?? I want to bore scope my cylinders to check before I sink one more penny in this car as much as I love it.

2. If my cylinders are clear of detrimental scoring, is it possible to put the m157 oil cooler setup on the m278 engine? I watched a video by Tasos and he was working on an m157 and mentioned the major deterrent to m278 engine scoring is to put the m157 oil cooler and supporting lines on the m278 engine. Did I hear this correctly or was my coffee way too weak and misunderstood him?? Anybody ever done this and if so how is it working for ya and a link or something on parts to do so??

are you serious wtf could give you a sound technical reply except scope all your cylinders----but the bigger question is why do you think any of your cylinders are scored

because its an m278 engine. A quick google search pretty much answered my questions but thanks.

check latest oils - designed to reduce LSPI (low speed pre ignition) - on crappy direct injection designed to die engines

You might check out the oil pump solenoid thread and the latest recomendations. Disable the solenoid by unplugging it and then get a new one and install to the unplugged harness and zip tie it up out of the way.. Then change to 5w-40 oil to allow for full oil pressure at all times.

Yes that thread is hugely long but well worth the read.

Contact Calibenzdriver on that thread for details and suggestions for your particular car.

What's your mileage?

Send an oil sample for analysis to Blackstone Laboratories. I did that and they mentioned zero metals indicating cylinder scoring.

Change your oil at max 5k miles and drive it very slowly until warmed-up and you should be more than fine.

This ^^^. Never flog it when the engine (oil) is still cold.
It takes another couple of miles after the (water)temperature needle reaches the middle of the gauge before the oil is warmed up too.

Cooldown is important too - for the turbo and for the oil in the turbo. So either drive the last mile very relexed or keep the engine running for a minute if you came in hot.

This is the circulatory "blood" of choice changed every 3000 miles and always has been .

My question is still......can a person with an m278 put the oil cooler setup from an m157 setup on the m278 and it bolt right up?? Tasos had mentioned something about it but I can't find the video

The M278 engines have a tendency to score themselves??

Yeesh.

direct injection causes low speed pre ignition - unless the perfect situation of oils they hadn't invented are in the car, the right fuel they don't sell any more is in the tank, and the gearbox ALWAYS allows the engine to operate comfortably inside an area of its power curve it seldom achieves

the deliberate damage LSPI provides destroys the cylinder coating, thus ensuring designed to fail poverty and planetary destruction lands to its correct timeline

Is the engine just running too lean? Does the oil need an appropriate (higher) flash point? Could a tune solve this by enrichening the mixture under idle conditions?

229.72 oil is designed to reduce the damage caused by LSPI that is inherent in the disaster that is direct injection
