So the lifter tick and large amounts of smoke have not stopped since head replacement, put the snail in the shop to get issues sorted. Fingers crossed all sorted and running better than ever by this arvo.
Dying to have her back up and running like new.
best wishes for Snail :-)
I'm interested in your comments when the Snail returns, hopefully all good news
all the best for the snail might be a bent rod
Let us know how she goes. It could be a cracked piston, bent rod etc. Or even something as simple as the head not being torqued down correctly. Either or good luck
Ok, so she is back from the shop. Mechanic recomended glow plug change to fix smoke and rough running on cold starts, so I did that this arvo. As for the tick, it is an ongoing saga. It has been discovered that tick only occurs whilst car is in gear and being driven, not present at idle or high reves whist in neutral or foot on clutch. Mechanic suggested more sound insulation under gear stick boot, I dont believe this is the answer as noise was not there prior to doing timing belt and head reco. He did full pressure test and found all good there, no loss in pressure, so thinking this rules out piston or head issues. I also reckon she is down on power, also noted oil pressure good untill warm then whilst at idle all pressure drops until revs up again, mech tells me normal due to less resisance with warm oil. Any furher suggestions would be greatly appreciated.
Sounds ok, oil pressure normally half guage going along and drops at idle thats with after market guages, stick screw driver to ear and pin point the tick, Have you got a short shift in your GQ???
Not on a trol but my Isuzu ute with 4JB1 engine used to have similar problem..ticking sound from the engine, some black smoke and lost of power below 2000rpm..turned out to be IP problem. Not a serious problem though, a day in the shop and cost me around $200AUD..
Just a thought..
Have you ever done the advance plate on the pump? Is it hard to start sometimes?
Cheers for all suggestions.
Yesterday evening whilst dropping the boy at footy the noise was worse than ever, even started at idle now, by chance I was driving past mechanics and he was still in. I dropped in and let him hear it now car was up to full temp and had been driven for a while. He def thinks it big end bearing and main shell. So back into shop today to have sump pulled of and thses things checked. He said when the pistons hit the head it prob would just transfered the impact to bearing. Im thinking he on right track now. Hoping should be all good by weekend now.
bottom end pulled off and all bearings reported to be in A1 condition. Now saying "yep it the tappets that need replacing" sure this is what I said when I took it in, jesus. Now going to set me back 1500 bucks due to work done today and to have them fixed. So annoying this rubbish.
Costly but at least its all sorted now for years of trouble free 4x4ing
You meant the rocker arm? Could be but my rocker arm on the old engine were in pretty bad condition, badly scored on the face where they in touch with the valve but it didn't produce any ticking sound.Quote:

Find a new mechanic this guy sounds like a joke
Hope you're not paying for his thinking time?
I think the ticking is coming from a rock in your tyre lets just replace them all and see if it works.
I recall your other thread asking you about the oil pressure and you responded.

Yeah engine has had really good run. Oil pressure is spot on.
Are you sure your mechanic put the oil pickup back in when the done the big ends lol

Got new lifters under warranty, and thinking mech timed it up wrong. I checked it and it was out slightly. Sorted now and memories of how much I love my patrol coming back. Can't wait to hit the tracks.
Good news at last!!!!!
Good to hear it's sorted i hope you avoid that mechanic in the future lol
Excellent stuff, so where's the detailed report with pictures then? ;)
Bloody fantastic, you sure got screwed by your " mechanic".
Stick to the forum even if to find a decent mechanic in your area.
hit those tracks buddy
guys what the word?
i got ticking on the rb30 after valve timing and oil/filter change. not too worried though.
i figure its the thiner oil caz what came out was thick and black, now its still nice and yellow.
was gonna get a second hand head and maybe swap some stuff around between them
