rudd86 Posted September 26, 2012 Share Posted September 26, 2012 did you keep the 200tdi disco item and drill and tap....? or did you use a 19j (your old engines one)....? I used the 19j as after a load of searching on the net that was the way I thought people did it. now my mechanic that is fitting my new crank seal says it wont last unless I re-fit a proper disco 200tdi one with the mentioned drilled and tapped holes. I need to make a decision what to do now, bit of advice would be good. Quote Link to comment Share on other sites More sharing options...
reb78 Posted September 26, 2012 Share Posted September 26, 2012 I'm pretty sure a lot of folks have used the 19J one with no issues at all. Having said that, its not a big deal to drill and tap the disco version and then your timing holes are in the correct position. Quote Link to comment Share on other sites More sharing options...
nickr Posted September 26, 2012 Share Posted September 26, 2012 I used the Discovery flywheel housing. Originally had counter sunk bolts to fit but decided to Counterbore rather the Countersink and use Cap Screws in the end as i felt that the stress would be less of an issue with cap screws.

Phil Hancock Posted September 26, 2012 Share Posted September 26, 2012 Cap heads every time as yoiu can not tighten CSK heads to the same extent due to the hex key being smaller on a csk. Quote Link to comment Share on other sites More sharing options...
Briarston Posted September 26, 2012 Share Posted September 26, 2012 Disco housing. The holes are already there, just need opening up to tapping size, and a couple of studs to relocate. As already stated, Disco housing lower half is fixed to the ladder frame, 19j one is not. Although others say this has been no problem, I think there is the potential for the joint between the housing and block to ease, resulting in a oil leak before it reaches the crank seal.

ejparrott Posted September 26, 2012 Share Posted September 26, 2012 The only problem I'm aware of is that the 19J timing hole is at the top, the defender/disco 200 is at the bottom - I don't see how you can time the crank, unless the flywheel housing drain hole is the right size.

Phil Hancock Posted September 26, 2012 Share Posted September 26, 2012 Another way of looking at the disco/def housing versus using one from an earlier engine to avoid the bottom bolts is that Landrover saw fit to introduce those bolts (with the cost of modifying the patterns for the castings plus the bolt costs) for a reason not just a whim.
