Thumbs up Walnut Blasting by e90TiAg335i (REVIEW)

So this past monday i got my valves cleaned and figured id write a small review on it and my experience for us folks around the southeast/florida

So for the past couple of months i have noticed a little hesitation sometimes at lower range rpms..sometimes at higher range rpms, i have also noticed a small jerking and erratic idling at stops so after changing the spark plugs, checking coils and getting the hpfp tested i some research and came to the conclusion that considering the mileage on my e92(118k) i figured the next best thing to do would be some valve cleaning.

After looking around for places and peoples personal experiences i chose to go with with e90TiAg335i(Brett) in Jacksonville FL who came highly recommended by some members on the forum, since his price at this moment is very reasonable($250) and his proximity to where i live isn't bad the choice to go to him was made easier.

As far as Brett he is very honest and very knowledgeable about BMW and seems to have every tool known to mankind on his garage , from what i could tell he has performed this procedure plenty of times before and he made it seem easy. As far as his work, he does the valve cleaning thru the method of walnut blasting and uses the procedure mostly any other shop will use, he doesn't take any shortcuts and will blast it as many times needed and use as many resources necessary..but i will let the pictures speak for themselves.

BEFORE








DURING



AFTER








COMPARISON







My immediate thoughts afterwards were WOW! The delivery of power was much more smoother, the car seemed more responsive and the sympthoms i had before have ceased by like 95%. Now on day 2 the car is running great and feels like a new car in comparison to before and it is safe to say it runs as smooth as my e90 335i i drive for work which has under half the mileage.

Bottom line; if you haven't done this, DO IT! it will rejuvenate your car and engine and it will make it fun to drive again..if done by a skilled person there isn't a single negative outcome that can come from this. If you are in Florida or the southeast make sure to hit Brett up and he will get you taken care of at a reasonable price and will do excellent work!



NOTE:this pictures were taken with a cellphone so sorry for the quality but i can provide with better ones.

You'd be surprised..they werent as bad as imagined if you consider the mileage. He had seen cars with less mileage and worse buildup. But yea iam glad as well.

I could be wrong but I'm willing to bet you it even happens with one. Granted, it'll hopefully be much less. I'll know soon as a friend has me do his and he's had his OCC for quite a while.

They do get pretty dirty but the OCC helps a lot, the N54 get a lot of oil blow back from the crankcase and all gets dumped to the rear turbo and eventually makes it was to the intake ports.
I think is great that you are doing this for a great price, I've heard the dealership charging over 1k to do this same job.

yea even cars running occs and meth still develop their share of buildup so its never a bad idea, i would suggest for anyone with over 50k miles on the clock to do it..specially at a price like this its a win/win, to Brett for helping out the BMW community
