engine noise level

[Pajero]

Just have a question, has anyone noticed a big differance in the noise coming from one engine to another?? when I bought my 94 Paj LWB 2.8L my friend also bought a 94 Paj 2.8L SWB his engine was way quieter than mine especially when parked and reving the engine a bit. mine would almost hurt your ears and his was no where near that level.....

Any I deas why this would be? has bugged me for a long time now...both seem to run the same..

Thanks

Possibly a hole in your exhaust? Or the manifold?

when i was looking to buy my truck i looked at 4 from 91-93 and they all had a strange sound to them. and it all seamed to be a exhaust leak or a loose heat sheald. the one i bought sounded real bad at first but i grabed the heat sheald with a glove and then it sounded fine. so id say take a look at your heat sheald first

no its more just the diesel clacking sound

Check the oil level and adjust the valves (clack clack sound)

[92Nicopolis]

yeh.. im not sure whythey would have a clack but the valves would mak the most sence to me

[Pajero]

I think everything is fine, after I got it I took it to cvi and they did a delica tune on it
It runs great but not sure why his would be quieter... I should take a video of it and post it...will work on it

[pajerry]

For the 'clacky' valves, is it just a matter of tightening them up?


EDIT: Sorry, a quick google set me straight!

[Modsqwad]

The valves need to be adjusted with a specific clearance to account for heat expansion of the valve stem. I can't remember what it is for our delicas but I'm sure its available with a quick search.

PS Just noted the Deli Tune from CVI. From all I have heard of their service this would have been taken care of at that time.

Hi Guys,

My l400 is in very good condition. I have it tuned @ CVI too. I am very happy with it. It does has louder engine sound more than I like and I believe its due to the valves .( all oil & filters are changed) I asked Butch whether he can adjust the valves so it will be quieter . He advise me not to . He told me to adjust the valves ,it needs to shim them and then the engine will not run smooth. So from that time onward ( about a month ago ) I never bolder anymore cos I have faith @ CVI as much as anyone in this forum who knows him. I do notice that the engine sounds quieter when the weather is warmer.

This is what I understand and if there is any other advises will be very much appreciated.

Couple videos i took.

Cold start up

Engine warmed up, when i took this it looks like the oil pressure sensor is leaking a focused in on it at the end, is there a gasket for this or is it just a remove and teflon tape it up??

I could be way off, but it sounds like your revs are quite low!?

[Pajerist]

Cold start up http://www.youtube.com/watch?v=Ag2KQVy6tn8

Cold start idle should be 800 RPM, (you have about 500 RPM),right after start up increase RPM to 1100-1200 for 2-3 minutes, maybe 5 minutes more if temperature is -10 degree, (BTW, your truck starts good) then drive without hard acceleration for 5 more minutes. What is your oil level? What oil do you use?

[Pajero]

oil level is good i use shell rotella synthetic 5W40, although I should check it again as the oil pressure sensor seems to be leaking.....hmmm and japanoid replaced that for me before.......how do I go about re-sealing this?

Thanks

Thats weird i have the exact same pajero colour and everything, not that that matters. But mine doesnt have that clack sound at all. The coldest I've started mine was minus 6 after sitting overnight and it didnt have nearly that much trouble. Sounds like your valves are out of wack.
