Ex Member Posted February 29, 2016 Share Posted February 29, 2016 They are just regular 8 mm bolts. Nothing special. FB108101L [M8 x 50 - flanged head ] http://www.allbrit.de/UNI.cfm?PAGE=748198&SPRACHE=EN http://www.turnerengineering.co.uk/acatalog/FB108101L-Bolt-Flanged-Head-983.html Make sure you blow out the holes first and properly torque them. Worth re-checking torque in the future. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 29, 2016 Share Posted February 29, 2016 Note the bolt size is contained in the part number... http://www.ep90.com/index.php?id=28 FB = Flanged head bolt. 1 = metric 08 = 8 mm 10 = 50 mm long 1 = passivated zinc plating Quote Link to comment Share on other sites More sharing options...
tonydrover Posted February 29, 2016 Author Share Posted February 29, 2016 That was the part number I found too (eventually) the ones I took out were definitely 10mm though Quote Link to comment Share on other sites More sharing options...
tonydrover Posted February 29, 2016 Author Share Posted February 29, 2016 Re the EGT gauge.....Red90 Its a Saga 2.0s. Bought it ages ago, just never got around to taking the manifold off to drill and fit it. A bloke at work (who knows his taps and stuff) told me 1/8 TP was the Jap equivalent to BSP (British Standard Pipe I think). Quote Link to comment Share on other sites More sharing options...
Ex Member Posted February 29, 2016 Share Posted February 29, 2016 That was the part number I found too (eventually) the ones I took out were definitely 10mm though 10 mm spanner for the bolt heads. 8 mm diameter threads... Are you saying yours are 10 mm threads? Hopefully not as the bolt goes through the rocker shaft. Oil flows along the shaft. A larger bolt would be a bad idea.

A bloke at work (who knows his taps and stuff) told me 1/8 TP was the Jap equivalent to BSP (British Standard Pipe I think). Japan uses BSP and they call it PT (not TP) although it should properly be called JIS. 1/8" NPT is 27 threads per inch. 1/8" BSP is 28 threads per inch.... Should be able to tell with a thread gauge, if you are careful. Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 1, 2016 Author Share Posted March 1, 2016 Red90. Re Rocker bolt.......It was 10mm spanner I was referring to. Pretty sure you are correct with the thread size, certainly was narrower than the head. Re the tap...... I did mean PT not TP, so that should read- 1/8 PT Quote Link to comment Share on other sites More sharing options...
mmgemini Posted March 1, 2016 Share Posted March 1, 2016 Sorry Tony no bolts. rocker shaft is there but no bolts Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 1, 2016 Author Share Posted March 1, 2016 Thanks for looking Mike, I've ordered some new ones now. Just taken the head into the engine place in Darlo. One of the glow plugs sheared when I was taking it out, but the fella there wasn't phased by that. Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 9, 2016 Author Share Posted March 9, 2016 Got the head back now, and what a nice clean head it is (Gmmmph ffnarr). No way can I put that back on the filthy block, so had to clean the block and the rocker cover yesterday. Blinking tipping it down with rain today, so rain stops play. Tomorrow hopefully! Question though? In the Landrover workshop manual it doesn't mention putting any gasket sealant/hylomar on the head gasket when you install it. Is that right? I can see it's not an ordinary gasket, so is that why? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 9, 2016 Share Posted March 9, 2016 Yes, head gasket goes on dry, just like almost any other gasket. No need for sealant. Quote Link to comment Share on other sites More sharing options...

tonydrover Posted March 17, 2016 Author Share Posted March 17, 2016 All back together now and running again, a few minor hiccups with the rebuild, but soon sorted. Even the EGT gauge system is working. Not sure what would be a normal temperature though. When idling it sits about 200 degrees. The highest I've seen so far under heavy acceleration was about 250-270 degrees. It hardly moves off the stop. I'm wondering have I put the sensor too far away?

vulcan bomber Posted March 17, 2016 Share Posted March 17, 2016 Where is the probe situated? Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 19, 2016 Author Share Posted March 19, 2016 The sensor is in the uppermost part of the steel down pipe.I was advised not to try and drill/tap the cast manifold, hence I put the sensor as far up the down pipe as I could get it. Had it out for a longer run yesterday, at a sustained 70mph it sits about 350 degrees. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted March 19, 2016 Share Posted March 19, 2016 The manifold is very easy to drill, I've done mine. Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 19, 2016 Share Posted March 19, 2016 Yep. The manifold drills and taps very well. Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 24, 2016 Author Share Posted March 24, 2016 One of the reasons I was told not to drill the manifold was the sensor could be too close to the 2 inner cylinders, and hence give a false reading. Where did you put yours? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 25, 2016 Share Posted March 25, 2016 The sensor tip is where all four gas flows meet. Quote Link to comment Share on other sites More sharing options...
tonydrover Posted March 26, 2016 Author Share Posted March 26, 2016 What temperatures do you get there? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted March 26, 2016 Share Posted March 26, 2016 The temperature is dependant on how you have the fueling setup. That is the point of the gauge, to set the system with the maximum fueling while not overheating the turbo, The turbos are designed for a maximum 720 C continuous inlet temperature.

tonydrover Posted March 26, 2016 Author Share Posted March 26, 2016 My fuelling is standard at the moment. Quote Link to comment Share on other sites More sharing options...
tonydrover Posted April 14, 2016 Author Share Posted April 14, 2016 Moved the sensor to the manifold where the four outlets meet just before it goes into the turbo. Temp at a sustained 70mph is now about 450 degrees. Quote Link to comment Share on other sites More sharing options...
