    Lifter damage picture

    Howdy all,mid tear down on a 3.9 engine replacement refresh.
    all the other lifters looked to have normal wear patterns,#8 cylinder
    looks like this.Foreign matter?

    Inspecting the spark plug in #8 showed it was the only one sooted up in the set,all others a healthy light tan.
    Amazingly the engine ran well,albeit a little down on power,as reflected in the #8 camshaft lobe,the others are evenly rounded off too

    This was replaced some 60k ago by previous owner,who had maintained the classic beautifully,and mentioned that cam was an original oem standard,knackered after 60k?
    Interested in thoughts on the wear pattern on that lifter,cheers

    Hi Westy1,

    In my research I've found that many 'oem' camshafts are not actually genuine Land Rover items. E.g. I use ETC6850L camshafts (pre-pollution Range Rover spec) on my 3.5L engines, and even though they are advertised as 'genuine oem' they only cost $80 - $170 and are of 'eurospares' brand or something. I've also purchased 'genuine oem' lifters from TWO reputable workshops and they turned out to be aftermarket items, despite having 'oem' on the box. They were definitely different to the Dephi lifters I've used in the past.

    Gidday Edward,yes indeed,was thinking the same,the previous owner did say he paid a premium for the camshaft but I had no further info on the source.

    I do know that most aftermarket camshafts,and possibly landrover boxed ones ,are made in Turkey these days,this confirmed from two sources,one being Pat at V8tuner in the UK.

    With that in mind this time,I got a camshaft made locally,$40 more than an off the shelf one
    Let’s hope their stock billet is better metal.
    Using Hylift Johnson A0896 lifters for gm/rover.

    The guy at the camshaft machine shop said they have had quality issues with generic lifters available these days for rover v8’s and even went so far as to specify using hylift johnson on the cam card!
    i didn’t buy them from this guy,already had a set,so was pleased to hear his recommendation and experience without anything to gain.
    Further to this,he strongly suggested not merely using high zinc oil for break in,but running it continuously,instead of my standard dinosaur Castrol gtx 20/50.

    Still intrigued why that one lifter was scribed like it is,when the rest,all oem supposedly,were consistent,so something else going on here maybe?
    Likelihood someone may have seen similar wear patterns and found out what the root cause was.cheers

    Just that one or two lifters lose their case hardening and then wear out.
    I had one so badly mushroomed that I had to drive it out.
    Usually after the cam shoulders wear.

    Hey..I seen this before on my previous Range Rovers...did not notice any roughness at idle or lacking power as it happened over time, but cam lobes worn down 2 of them..Replaced with a WL9 cam..Google it..it’s almost same specs as current 3.9 cam...I am talking late 80s when we all were trying to get more oomph from the Rover V8..my 3.5 made into 3.9 with new liners and Holden 186 30 though oversized pistons...spent a lot of money back then😳😁

    I second the comment that cams/lifters the quality of material used can be much poorer than in past. Particularly lifters.

    Got a set already Chevron,they look to be available mostly from cam machine shops,usually one in every town.
    As an aside,there are two Johnson companies making lifters in the USA,both just down the road from one another but not connected.go figure,with Hylift Johnson being the original.

    Seemingly causes quite a bit of confusion amongst the LS engine build fraternity..
    Hylift is a name,and doesn’t refer to high lift type lifters too,as I found out.

    I think it’s great to see a small town family business thrive due solely to their name getting out there for their quality.
    No more expensive than an oem set either,mind you I got a bit of a deal.

    My sick mind went to a good old boy from Muskegon greeting some corporate suits who came a callin,with a shotgun,haha
    Aftermarket/oem left,Hylift right.

    I have this same discussion with Mercedes owners. Research on supplier parts sourcing and rebranding point of origin etc. "mandatory" for all parts sourcing.
    By the time you stuff around, a genuine MB boxed part with 2 year warranty for a price premium of up to 40% over the aftermarket junk, is actually a sensible insurance policy.

    Having said that, Lemforder (who do LR parts as well) are almost always a high quality OEM, for many of the drivetrain stuff.

    Good to see you have found quality parts and supporting good small business instead of buying crap quality from overseas.

    Hi Westy1,

    Some good insights you have from people in the industry there! It's also handy having that part number for the Hylift Johnson lifters. Recently I tried to purchase some Delphi lifters, and I had two different reputable parts suppliers give me two different part numbers, and they were different to the part numbers published on this forum!

    So far my experience with the cheapo ETC6850L camshafts has been pretty good. A tear down of an engine with 130,000 km showed very little camshaft and lifter wear. A recent tear down of my current engine at 60,000 km (to fix a broken piston ring) showed very little camshaft wear, but some very slight pitting on the lifters. I use Penrite HPR-30 when it is on special, but mostly use generic 20W-50 because it is so much cheaper (just picked up 5L of GTX 20W-50 on special for $12, compared to HPR-30 for $40! I can't argue with my bank balance!). In the future though, I will invest in a better quality camshaft for peace of mind.

    I cannot explain why your rear-most lifter has worn, but I do remember my Dad a while back drilling two small holes at the back of the Rover V8 valley to let more oil spill onto the rear-most cam lobes. Perhaps he heard that was an issue with this motor, or perhaps he was trying to prevent the issue that occurred to our 308 Holden which chopped out the rear-most cam lobe due to lack of lubrication.

    Edward
