JimAttrill Posted July 24, 2019 Share Posted July 24, 2019 The genuine 300tdi manual says that the connecting rod nuts should be changed but there is no mention of the bolts. Should those also be changed? My engine has 330 000 kms on it and the nuts were changed at half that when I changed the rings. This time it will be a complete overhaul with new sleeved and pistons etc. Quote Link to comment Share on other sites More sharing options...
western Posted July 24, 2019 Share Posted July 24, 2019 My 200 has in excess of 500,000 miles, didn't replace the con rod bolts at my rebuild, engine is running fine Quote Link to comment Share on other sites More sharing options...
Alhedward Posted April 13, 2021 Share Posted April 13, 2021 Conrod bolts need to be changed if you find any difficulties spinning the nut by hand onto the conrod bolts all the way to the end of the treaded part. Any stiffness at all indicates a stretched bolt. This is from the genuine 300tdi rebuild landrover publication. Quote Link to comment Share on other sites More sharing options...
western Posted April 13, 2021 Share Posted April 13, 2021 The nuts are self locking so new nuts should not spin all the way down the threads by hand. Quote Link to comment Share on other sites More sharing options...

Sorry, the nuts are NOT self locking. They are 12 point flange nuts. Any other nuts are aftermarket or whatever was in the box of nuts and bolts on the shelf at rebuild time. Source for quoted directives from Land Rover: Publication part no. LRL 0070ENG 1997 page 68 point 9. states: “Using the fingers only, check that a new big-end bearing cap nut runs freely on each connecting rod bolt; if any nut is tight on the threads, renew both bolts on that connecting rod.” Nut part number is ETC8191 For completeness in this discussion thread, page 56 point 8. states: “Remove and discard 2 nuts securing each big-end bearing cap.” Note to moderator: Why the moderation if not to check accuracy of posted information? 97 300tdi rebuilds and counting. Edited April 14, 2021 by Alhedward Incomplete information. Accuracy is extremely important and very rare. Quote Link to comment Share on other sites More sharing options...

The same reason as most forums, to prevent blatant spam and trim up people who turn up with an attitude. 4 Quote Link to comment Share on other sites More sharing options...
monkie Posted April 14, 2021 Share Posted April 14, 2021 The fact checking responsibilities surely sit with the person taking the advice. Often what is stated on here is a case of "this is how I did it and this is what happened" as in Western's 200Tdi rebuild. There is no obligation to take the advice or contribute to the forum. Anyone who isn't satisfied is free to go elsewhere and write us all off as a collection of idiots as far as I'm concerned. 1 Quote Link to comment Share on other sites More sharing options...
