catwrench55 Posted October 31, 2017 Share Posted October 31, 2017 Driver said she started knocking and blowing out the blow by. Went and drug it home, got the heads and own off still haven't found the obvious problem. Had to go get a socket to remove the rod caps so surely will figure the damage tomorrow. No chunks in the own but plenty of different types of shavings. Open to any tips as first time this deep in a dog .

catwrench55 Posted October 31, 2017 Author Share Posted October 31, 2017 1.3 on chasis. No history. I've put about 20000 on it. Friend bought it at an auction in Arkansas, decided he didn't want it I bought from him. The heads looked new when he brought it home. Had a oil leak on the right side cylinder #3. Head gasket.

turckster Posted October 31, 2017 Share Posted October 31, 2017 More than likely spun a rod bearing. Personally I would go the exchange engine rout. You get an engine with a year warranty that has new/reman components in it. I would definitely replace the oil cooler and take a close look at the turbo and air compressor. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/51554-overhauling-a-2001-etech-427-open-to-sugestions/#findComment-383919 Share on other sites More sharing options...
catwrench55 Posted October 31, 2017 Author Share Posted October 31, 2017 Yeah just hard to justify dropping 25k in a truck I paid 9k for. If the crank is bad idk what I'll do tbh. I like the truck other than the 10 speed, just re did all the floor in the cab. Would a 60 series fit in there? Not many good pull out Mack motors in my area.

catwrench55 Posted October 31, 2017 Author Share Posted October 31, 2017 Well #2 Rod bearing stacked crank trashed. Here we go. Will a 60 series or a n14 fit in a CX? Local shops in $4500 to $5000 exchange for take out mack engines Quote Link to comment https://www.bigmacktrucks.com/topic/51554-overhauling-a-2001-etech-427-open-to-sugestions/#findComment-383960 Share on other sites More sharing options...

Dirtymilkman Posted November 1, 2017 Share Posted November 1, 2017 What causes a rod bearing to spin? Besides heat? Just curious.

Excessive idling can result in an oil film that can't support the load needed. Engine lugging can distort the crankcase and/or crankshaft, causing rapid wear the connecting rod and / or the main bearings to name to most common causes Edited November 1, 2017 by 41chevy Quote "OPERTUNITY IS MISSED BY MOST PEOPLE BECAUSE IT IS DRESSED IN OVERALLS AND LOOKS LIKE WORK" Thomas Edison “Life’s journey is not to arrive at the grave safely, in a well preserved body, but rather to skid in sideways, totally worn out, shouting ‘Holy shit, what a ride!’” P.T.CHESHIRE Link to comment https://www.bigmacktrucks.com/topic/51554-overhauling-a-2001-etech-427-open-to-sugestions/#findComment-384065 Share on other sites More sharing options...

catwrench55 Posted November 15, 2017 Author Share Posted November 15, 2017 Well got a new to me rod finnally. Have quite a few hours polishing the crank. Hopefully tomorrow will throw it in with a new bearing and some plastigauge. Are the rod and main bolts torque to yield one time use?

catwrench55 Posted November 16, 2017 Author Share Posted November 16, 2017 Apparently I polished more than I thought. Standard bearing with .003 to .006 plastigauge on top and bottom barely flattened at all. Guess ill put the top back together and wait for a .010 over bearing to try.

catwrench55 Posted November 20, 2017 Author Share Posted November 20, 2017 Well found some good calipers to find my crank is .020 out of round. Back to square one guess I'll see if anyone in the fort worth area wants the truck as is. 2001 etech 427 Fro16210 Hendrickson air ride Merritor .370 Quote Link to comment https://www.bigmacktrucks.com/topic/51554-overhauling-a-2001-etech-427-open-to-sugestions/#findComment-385429 Share on other sites More sharing options...

catwrench55 Posted December 9, 2017 Author Share Posted December 9, 2017 Sorry haven't checked in for a while. Also can't get pictures to upload off my phone. I'll send them by email to anyone that is really interested. I would take 5k for it as is.

catwrench55 Posted December 9, 2017 Author Share Posted December 9, 2017 Also, I have found a good 350 etec. Would i be good to go with my ecm, injectors, turbo, and cam keyway. Any other differences from my 427?

bts-4120 Posted December 13, 2017 Share Posted December 13, 2017 i yeah that should do it unless the balancer might be diffrent. if I was going that deep in the motor to do all that you might as well freshen it up with a in frame kit and new cam though Quote Link to comment https://www.bigmacktrucks.com/topic/51554-overhauling-a-2001-etech-427-open-to-sugestions/#findComment-387375 Share on other sites More sharing options...
