engine tapping ...oh no

[IndianaVX]

thanks guys
yes, i am suspicious of the exhaust rattle, not real concerned about it, but it will be found and dealt with....
Joe, i have owned the vx for a year, and changed to mobil 1 2 days after i got it. so its been running mobil 1 for a year. i also run the lucas syn oil stabilizer. and run the lucas gas additive...(forget the name) for cleaning the top end.
there is no noticable power loss, i cant make the tapping. it just happens. have heard it once today.
thanks again guys for the intrest, and input.....its appreciated
lunch is over... gotta get back at it!

ok, i think i got AUDIO, and a pretty lousy video, but it is the sound im after....take a listen. its not the best sound quality, and it is loud because i stuck the camera right down in there. camera location is just above the spark plug closest to firewall, on drivers side. i used my stethescope, and it is defenatly loudest there also. i put the scope in the indented groove on the "valve cover?" just above the spark plug. i also stuck it in the indent around the spark plug. both places it was very distinct tapping.
so, if this works, heres my audio clips.......

ok, thats not working....posting the video, that is.....ill try something else

It sounds like you may need the valves adjusted. It says in the manual they should be checked every 60,000 miles. shawn

After taking a look at our shop manual I have to concur with psychos2 that we do not have the hydraulic type lash adjusters, as they look like good ol' bucket tappets:


Now I'm all curious where this "hydraulic valve lash" info came from referencing the 6VD1 and 6VE1 engine. Oh well, another challenge.

My apologies if I led anyone astray!

That doesn't sound good at all! Sounds like an old mercedes deisel.

[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,

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
