Snagger Posted December 16, 2017 Share Posted December 16, 2017 Mine gives the same figures as Mav, even just after rebuilding with new crank bearings (no regrind, but the crank looked like new). I didn't replace the cam bearings and I did reuse the oil piston oil jets, so the loss may be in one of those areas. It burns oil too, despite a rebore and new pistons, two head rebuilds and two replacement turbos. I wish I had your success, Ralph! Quote Link to comment Share on other sites More sharing options...
western Posted December 16, 2017 Author Share Posted December 16, 2017 I reused the piston oil jets but with new relief valve bolts, maybe one or more of your piston ring gaps have moved so the gaps aren't away from each other. Quote Link to comment Share on other sites More sharing options...
Snagger Posted December 16, 2017 Share Posted December 16, 2017 I used the old bolts, so that may be responsible for the lower pressure. I was told by several sources that the cam shells seldom wear, and that they are unlikely to be an issue unless they have slipped. I put the ring gaps at 120 degree intervals so all were evenly spaced. I was fairly gentle with the running in and started with vegoil after 1000 miles, and that did coke the pistons a bit, so I wonder if it's glazing that is responsible for the oil burn - it's worst on over-run and idle, and minimal when working hard. Anyway, that's a great job on yours. You should be very pleased with the result. I guess starting is really easy in the cold weather, too.

western Posted December 16, 2017 Author Share Posted December 16, 2017 It's starting very well, I had to replace one of my batteries early this week, it wasn't holding a charge even after being on charge all day/night last saturday, had it tested & was advised it was dead & required replacement, so 2 good & healthy 900amp batteries on board, 1 for vehicle/starting & other for the winch. doubt your ring gaps have moved then, mine were spaced similary. reckon I'll be doing the 1,000 mile oil & filter change this coming week.

western Posted December 21, 2017 Author Share Posted December 21, 2017 Obtained some semi synth 10w40 engine oil & a good quaility oil filter, so tomorrow after work will see the mineral oil & filter dropped after just over 1000 miles, the new stuff is going in for the next 6,000 miles, engine is running very well & feels much smoother to drive & quieter.

Soren Frimodt Posted December 22, 2017 Share Posted December 22, 2017 I clearly visit the Defender Forum too infrequently! I totally missed this great thread! Top job Ralph Lovely to see Land Rovers best ever Diesel engine getting the love it deserves, and I'm sure it'll give you many many more happy miles 2 Quote Link to comment Share on other sites More sharing options...
western Posted December 23, 2017 Author Share Posted December 23, 2017 Long drive over, all went fine, new semi-synth 10W/40 oil, oil pressure at a constant 48 psi & coolant temp max at 88 degrees but dropped back to 80/85 when not pushing hard, oil temp got to 110 degrees when climbing hills, sounds quiet even at 65/70 mph. I'm well happy with the rebuild. 1 Quote Link to comment Share on other sites More sharing options...
Arjan Posted December 23, 2017 Share Posted December 23, 2017 I'm going to print this one and read a few times. On the to do list is swopping a 300 Tdi as it is not just smoking - it is tryinf to cause a black out in the Allier.... 2 Quote Link to comment Share on other sites More sharing options...
sonoronos Posted January 5, 2018 Share Posted January 5, 2018 Love this thread, thank you so much for the information. I am doing a head job on my 200tdi now...not nearly the full rebuild you have done! I have a question about the headgasket: 1. What was the original headgasket that was installed on your truck (when you removed the head)? Was it an MLS headgasket? 2. Is there any particular reason you went with the composite headgasket on your rebuild as opposed to the MLS? 3. Do you have any idea about how many miles the composite type headgasket will last (in miles)? Do you think it will be as durable as the original headgasket that was in your truck? As you may surmise, I'm trying to decide between using the MLS headgasket (Reinz) or the Composite type (Elring) 1 Quote Link to comment Share on other sites More sharing options...
western Posted January 5, 2018 Author Share Posted January 5, 2018 The previous head gasket was the normal composite type NOT the laminated steel thing, I had one of those sometime ago & it allowed coolant & oil to mix, so threw it away & fitted the normal type, engine original factory built with the composite type, so I have no worries about it not lasting for years, IMHO the MLS type is total rubbish. the currently installed gasket is a Elring Quote Link to comment Share on other sites More sharing options...
