engine tapping ...oh no

[Tobert]

Mine sounds just like that and has ever since I got it. I've put almost 10k on it and no problems yet. It is rather annoying though.

[Cyrk]

Mine was sounding like that... I could not totally tell with my S/C and exhaust... but brought to my Mechanic, and he did a valve adjustment on it.

I have around 55K miles on mine.

[IndianaVX]

yeah, im thinking it sounds like a 3.5 desil... ive decided to do the seafoam treatment. got 3 miles on it so far. will do an oil change in 497 miles, if its still tapping, its going in for valve adjustment, ugh. hoping the seafoam will clean it out though, which im sure it will, but not sure it will stop tapping. could have probably used the cleaning anyway.
keep the replys comming though. it sounds like theres alot of valves needing adjusted.......lol.
thanks peeps,
david

UPDATE
ok, im gonna change the oil, with the seafoam in it, on saturday, that will put it at a little over 400 miles with it in there. the tapping hasnt gone away...hasnt gotten worse either, but i will tell you something thats come back........MY MILEAGE!!!! more on that in a minute
QUESTION i got the stethescope out again today, and was listening, and i may have found my tapping. there is a square box, on the same mounting as the fuel pressure regulator. seems to be a valve or solenoid of some sort, maybe a purge valve or solenoid, and there seems to be a piston in there somewhere, cause its tapping like theres no tommorow. anybody know what im talking about, had this problem, or has anyone replaced this part, and why?? i looked thru tones manuel, and you can see the part im talking about in the picture of the fuel pressure regulator, but it doesnt identify it.
HELP NEEDED

ok, now for the better news. after a can of seafoam in this tank of gas, wiffing half can thru the pcv, and having half a can in the oil, mobil 1 with lucas syn oil stabilizer,
and a whole week of little 8 mile trips, all in town driving, zippin all over the place, i got 297 miles befor the light came on, and even it shut off when i came into the driveway tonight. for me that is excellent. in theroy, i should have around 320 or so miles if im doing highway miles in there too, maybe. but this is great news for me. the short trips have been killing my mileage lately.
so, im asking again for help from you guys on the identifying of the part described, and any opinions on if this makes sense on my tapping issue.
thanks in advance
waiting patiencly for a response

Is it the egr valve? There is a nut on the bottom that can come loose and rattle. shawn

[IndianaVX]

no, its not the egr........its on the back side of the engine, by the firewall, on the drivers side. just above the back coil pack, on the drivers side.theres a bracket, that holds the fuel pressure regulator, theres a hose with a light blue,(i think) cap on it, and nestled in this bracket is a silverish box, and the tapping is REALLY loud when i listen there with the steth. dont know what it is, but it sure is making alot of racket. dont know what to ask for to replace it, or even look it up on the board..........hmmmmm

That silverish box with the blue cap...sounds like you're describing one of the ports in the A/C system.

I bought mines with that tapping too.Now it taps harder when it's cold,but after 5+ minutes the taps breaks down quit away.

I was concern about that,so i had an isuzu specialist checked it,he said that tapping happens because the VX were sit for a long,long period of time,my VX were storaded for almost 5 years in massachusset before the son of the previous owner's (who died) decided to get rid of it,that's why my VX only had 38K on the clock when purchased on november last year,he also said that will not cause any damage to the engine,neither the engine's performance. I've add almost 5,000 miles since & truefully the VX runs very smooth,it starts rightaway & never give me any troubles so far.

My mech told me to use 5w 20 mobil,but i didn't supposed to add lucas oil stabilizer,however i'll have the VX into the shop as soon fall season shows up to correct that little annoying noise.The tapping is right under the left cover or passenger side.

I finnally ran out of brake pad on my VX. When I did, I figured I would replace rotors and pads; I also wanted to strip and paint my calipers, they have a rusty surface. I got the car up in the air and ROTORS don't come off like anything I've ever worked on! Looks like you have to pull the hub? How difficult is this? Is this when people do bearing repacks also? I might just paint my calipers and puts the pads on; any advice is appreciated! So far my 2nd timing belt tensioner is holding, I checked it over the winter! Thanks! Erik

I quit sure many of the members had they caliper replaced at the own house so just check all related threads & you can figured how to do the job.

I replace my OEM rotors with R1 concepts drilled/slotted rotors & satisfied brake pads which i love how they performed together,excelent braking.
