Big Problems with an RD28, Need advice Please

[MudRunnerTD]

Hey guys we have a member that posted this in his intro and it has been overlooked and having recieved 2 pages of G'days i thought i would post it here and put a link to here in his intro for him

Can anyone help this guy out? Seems like a nice bloke other than owning a Landy, he is after all trying to fix a Patrol and our advice would be appreciated.

well hello ,what patrol do i own ??? well i dont !! dont like them never will !! sorry being honest

but i do have "well the handbrake has an r50 pathy yuk lol"
so why am i here you ask ?????

and im hopeing that with ol aussie ,help a bloke out attitude, i might be able to help my customer out.

i have an y61 patrol in the shop rd28 turbo, we have a new donk to go in,exh inj pump,new turbo,t-belt kit the lot,useing 5 x different manuels "and they all say the same thing, carry out t-belt fittment as follows
1- set crank to BDC keyway to "6 oclock and scribe mark to 3 oclock"
2-cam mark to t-cover
3-inj pump mark on sprocket to t-cover"and making sure the "9"is at same mark
3-fit belt "hmmm im likeing this "
4-inj pump mark to cam mark is " 25 teeth"
5-cam mark to crank scribe mark is " 51 teeth"
all good so far as per manuals !!!!!

6 hmmm some these might help

7-attempt to wind over , i can only get 40 - 60 deg clockwise and then bang it hits the valve ?? wtf!

8-we removed the cam to wind over bottom end to rule out fouling ,all good winds over.
9-re-fit cam try to retard crank timming by one tooth ? no good wont even wind backwards piston hits valves
10- advance crank timming 1 tooth ,still hits
11- advanace it 2 teeth and it will spin ok ,but now keyway is at "8 oclock" not at the 6 oclock as shown in manuals???
but ??? directly below the crank angle angle sensor is an flat marker "imagine a 30mm flat alloy bar protruding approx 40mm out of t-case with a grove all along the end " looks a lot like a timming mark but no book,manual or nissan bloke can tell me what that marker is ??

12-now ,called engine supplyer and told it should be good at those marks and that he gets plenty o calls of t-belt align issues.
and after speaking to the techs at the machine shop they work out how they went wrong.
the lifters are solids with buckets and shims so the lifters arnt hydroliced up !!
13- the cam is the same as the old one.


so please i beg of you ,has anyone had this happen ?? and do you know wat the flat alloy bar is ??

im a landie freak,so i should be able to work this out ,but it has me stumped

I'm guessing non of the usual techsperts have seen this yet MR otherwise it surely would have been answered!!??.................... even if he is a landy freak!!!! lol

do landrover engines turn the 'wrong way'?

This may help if you stick to it.

thanks guys
nah feret no good followed to the letter!
besides this is the 2nd donk we have done in 4 weeks "rd28 "and last one was no dramas???????
i personally think head is no good "ie valves set wrong but engine reonditioner says different ??

[albi]

i dont know why people dont like landies ?????

they dont leak oil !!

they mark their territory !!

and they dont rust !!!









to many oil leaks lolol

and it was a range rover that had the first coil suspention set up took a while for the others to catch on !!!!

then again i want to put gu diffs under a rangie!!!

Maybe there was some damage pre belt change?

Hey ferret I got mine running but there was a pretty big clunk going on. I'm think ing one of the valves must be slightly damaged, how else could I have broken that keyway without the crankshaft coming to a dead halt. maybe rebuild is the way... What ya reckon?

[the ferret]

Mate if you pull the cam and it turns over, the piston is not hitting the valve.
If you put back the cam, time it to the diagram, not advanced and not retarded, if it locks up, you must have lost the end off a gloplug.
This is an interference motor, any item inside the cylinder will lock it.
Pull the plugs and inspect.
You can't vary the crank/ cam timing on this motor.

A bent valve will cause a miss and white smoke.,Pull the glo plugs and see if they still have ends on them .
Other than that, the head needs to come off.
Has it been drowned at all?

If the key is at the bottom, it could be in any of it's 4 strokes.
.
You need to pull no 1 plug, turn the motor over by hand until pressure is built, (finger on gloplug hole) this means you are on compression stroke or exhaust stroke, continue to TDC.
Fit belt to marks on gears and timing cover by moving only the cam and see if valves 1 and 2 are closed, if they are open you need to crank 1 more rev to be at TDC no1 compression stroke re fit belt.
I think your timing is out..
EDIT.
Sorry, I meant to say fit the cam with lobes for valves 1&2 facing up. you will also need to spill time the injection pump to spill just before TDC before fitting the belt.
