Took the 2.0 to North east Machine shop last week.
their link Here's the news: Check align bore: Good Turn and polish crank: One over Magna flux (or whatever it's called) to test for cracks: Good Install threaded galley plugs: No problem Soak and clean case: Nice and shiney! Measure con rods: two are good, two are bad. Find and balance two new rods. Can you recommend a replacement? Find bearings "one over". $425.00 for the work and the rods. Sound reasonable? |

Ummn, you can't magnaflux a case...... Only ferrous materials can be magnafluxed- They are lying bastards if they told you they did this process to your CASE.. I inspect cases for cracks with eddy current checks if they are questionable or with liquid penetrant and a black light... You can only magnaflux things that can become magnetic.
So you need main bearings 021 198 483A or RAT 4038 in German.. This is STD OD (case) and .010 ID (crank) If you want first over OD (case) thats .020 and STD crank thats an 021 198 491 or RAT 4020. As for those rods- yeah they are toast and i would not trust that crank either... it takes ONE HELL OF A LOT to bend a 2 liter rod... Brazilian bearings are .001 larger ID out of the box than German.. The German are used in all my engines due to material content and tolerance.. The German bearings even weigh more in grams, hence them having more lead content. I get pretty tired of being the last resort for people- call me first and you won't have to worry about this crap... BTW_ I'd like to see pics of the galley plugs installed in the case- if they went too deep with the threading it can shut off the oil to two of your oil passages and destroy the engine in 30 seconds... I see it all too often. TIV specialist work on TIV engines- no one else. |
