You are only getting 105 psi? Something is out on that banks timing.


I missedmisse detail in the previous post.

Timing issue with valve not seated on compression ******?

That seems like it also might be consistent with unburnt fuel in he cylinder and a sooty plug.

I hope not, as I'm guessing that would necessitate another tear down.

Let us know how it goes.

you could pour a bit of Mystery Oil in the low cylinders and see if they come up. Spin over by hand a few times then re check.

When I did the Chains/Rails/VANOS on my L322, I also did a compression test on the motor, after it had been sitting for a week or so, the numbers were all over the place (100-180). Pour'd a teaspoon or two of Mystery Oil into each cylinder, spun it over by hand a few times, and the compression numbers came up. Once I got it running, I let it cool back down, and took another reading (hot and cold) and the numbers were all in spec, and less than 10% difference.

I'm not sayin you don't have a problem, with compression or somewhere else, just before you focus on compression test result, and tear back into it, I'd pour the oil in, spin over by hand, and retest.

Then before you try and start, pull all the plugs and clean them.

As far as why it's not starting, I don't know enough about these specific engines yet to offer advice, other then checking all of your connections, just the common sense stuff....

I am going to try this "easy" method myself. Just wanted to let y'all know the least expensive parts I have been able to find are at Land Rover FT Myers http://parts.landroverftmyers.com for:

Part Number Part Name Price Quantity Total
LR051013 Tensioner Guide $60.82 2 $121.64
LR087162 Chain Tensioner $31.45 2 $62.90

Subtotal: $184.54
Estimated Shipping: $11.27
Total: $195.81 quote]


I thought I had ordered: "Chain Tensioner" LR051008. I actually ordered the above LR087162 Chain Tensioner because the part was automatically changed in the cart. Original Chain Tensioner shows as not fitting my L322 5.0. Wondering if the tensioners have been replaced again by Land Rover? Will call parts office on Monday, but could use some help.

Pictures attached, guidance appreciated.

Looks like I just screwed-up and purchased the wrong tensioner parts accidentally. Odd that the Land Rover parts site says the LR051008 Chain Tensioners do not fit? I just ordered them as well from FT Myers Jaguar Land Rover:
Part Number Part Name Price Quantity Total
LR051008 Chain Tensioner $110.98 2 $221.96

LR051008 is in the LR parts schematic as #20, though you cannot see it unless you click tick to magnify the schematic.

Subtotal: $221.96
Estimated Shipping: $13.59
Total: $235.55

I might replace the other part number LR087162 (pictured) as well if it is not too difficult since I have them.

Yeah thats for the lower chain, not the ones you care about :)

Sorry for the delays in responding. I haven't worked on it since my back was hurting and was out of commission for a bit. I'm about to go tear it all down again for the nth time to check timing again.

I have zero codes. Compression on all 8 cylinders are roughly 190-210 psi, so I have good compression. First 3 seconds or cranks from the pressing the Start button it wants to start, but the later couple of cranks sounds like it's spinning faster or loss of compression. Not sure why and why I'm going back in there to do it all over again from the beginning without taking the intake manifold, TB, or water pump off.

One thing I did notice was when the rig was running and the first time I took it apart the timing markings did not line up. Even after tearing it apart every time it still doesn't line up, but the chain links were ALWAYS the same distance apart from the markings. If the chain markings were 3 chain links ahead of the markers, it's still 3 links at the other markers. Not sure if that's a huge concern, but just something I noticed. This sucks cause I went through 5 timing chain tensioners already and they're not cheap or reusable.

Before I rip it all apart, can someone do me a huge favor? I think it might be my crank position sensor (CPS) that's having an issue. If someone can use a multimeter and test 2 things, ohm reading and volt reading.

To do this:

Remove the CPS located on the bottom of the engine near the bell housing and the front drive shaft, it's held on there with a t30 bolt and 2-wire plug.
Once it's out set the multimeter (MM) to 200 ohm setting and have the MM black and red probe touch each lead on the CPS. Then set the MM to 20 DCV with each probe still touching the leads on the CPS, while holding the CPS wave a metal object back and forth over the tip to get a voltage reading. You may need to switch the red and black to get a proper reading, but it should read something.

Please report back with the results. Thank you in advance!!!

Oh and I'm getting.

Harbor Freight MM:
Anywhere from 0.01V to 0.05V (mostly 0.01V if that) and a quick flash of 46.9 ohms to 1 (no continuity).

All-Sun EM830 MM:
-0.00V to 0.01V (mostly 0.00V) and 1 (no continuity).

I'm really hoping its my CPS. Please let me know!!! I beg someone. :adore:
