Have had the p38 for a year now, has been wonderful.
Last week I noticed that after parking and engine cooling down a bit and back on it would slightly shake at idle for 10 seconds then go away. It has been driving fine after that. Also last week got a misfire on cyl 5 (p305 code), the service engine light was on. I cleared the code and has not popped up again (been about 200 miles). It also has been ticking only when warm, it sounds fine when cold and then will start a tick. I got the stethoscope out and its on the right side of the engine but can be heard almost louder on the right side tire well and under the car. Anywhere I put the stethoscope on the right side can be heard. Read the codes today and the p305 was not there but now have a p300 which I know is multiple misfires. I also took it for a drive with the nanocom plugged and it would throw misfires of cyl 5 (but the service engine light has not turned on and when I read codes with the nanocom it shows none)

I have read everything I could on the internet and a lot of cracked block/slipped liner. I want to figure this out myself and see if maybe its not something else because I go into catastrophe mode. Plugs, wires and coils have been done in the past 10-20k miles by the previews owner. Head Gaskets were done about 50k miles ago.
