Anybody know the purpose of these hex plugs under the intake? Should I remove them to clean this whole thing?

Hey, can you guys take a look at the close ups of my timing chain cover. I’m not sure if these are cracks, a failure of some coating or part of the die casting process. They look like hairline cracks to me and they feel rough to the touch. Anyone else have those?

 I've seen faint spider webbing on those casting in the past but nothing as prominent as those and never in those locations. 

you can buy them new for 75 direct from japan (I have one on the way) with expensive shipping its about 115$ I got one since I was nervous about reading how you need to check the boss the distributer shaft goes thru can wear and if it does need to replace the casting. I am sure that's overkill, seems like you could press in a sleeve, but anyway got me to looking and found it an Amaya. Anyway I will report what comes in the mail when it gets here. Paranoia strikes deep into your life it will creep...

That's the egr tunnel and you won't get those plugs loose, I tried.

You need an N42 intake. ?

And another front cover.

I think I have an extra front cover. I'll dig it out Saturday and send you some pics. Your's if you want it.

Another thing, that tunnel just has exhaust soot in it. You could take it to a spray car wash and blast it with hot soapy water.

Through the egr mounting hole? Pour some lacquer thinner down there? A can of oven cleaner?

Hell, use your N47 intake! No webbing. I forgot about that.

So, I sanded one of the areas I saw the spider cracks and I think it’s fine. I used 320 grit followed by 1500. Check it out now.

Any seconds?

So you bought a new front cover? Why? Didn’t follow what you said about the dizzy shaft?

the cover has a journal inside that the dissy shaft runs up thru. if it wollows out they say to replace the whole cover. Besides 100$ did not seem like too much just in case.
