Just wondering who you guys use for lifters. The missus' VN has an intermittent sticky lifter where it starts ticking and misses at the same time. The ticking stops and so does the miss. Am going to change the lifters but thought may as well do the timing chain and maybe throw a cam in too. Runs on straight LPG, any recommendations?

Mate that sounds suspiciously like a plug/plug lead miss rather than a lifter, more common on LPG too cos it needs a bit more energy to get a spark going. Might sound silly but watch it in the dark, you'll see it tracking.

Bugger me i opened me gob :)

No, it is a definite lifter tick. It only misses when it ticks. It comes in intermittently after it's been on a long run.

I might do that first. It does roughly 300kms a day so I'll chuck a bottle of lifter free in it tonight and change the oil tomorrow night.

After two days of driving 140km there and 140km back, it still ticks. One of the lifters may have **** itself.

Mate do your plugs and leads first.
vn/vp's lifters have to be REALY BAD before the engine would miss.
If injector free has not fixed it then it is most likley not the problem.
If you are going to do lifters cam and chain then just get a new engine.
Just about have to lift engine out to do that.

Update.

Yesterday fitted new leads and plugs, changed the oil and filter while we were at it.

2 leads showed no restistance, one lead was cracked and burnt with evidence of tracking.

However.....the ticking and the miss returned after about a 5 minute drive. Coasted in neutral and gave it a couple of revs, did nothing. Back down to 2nd, booted it up to 80kmh and the ticking stopped and she ran on all 6.

When it starts ticking you can hear it inside the car above the stereo....it's pretty damn loud.

You'd have to say sticky lifter for sure
