Volvo Penta D3 220 problem

[Beachworker]

Hello all..

I currently own a volvo D3 220hp which has done approx 270 hours..

there is a problem that the plastic inlet manifold splits along its bonded seam and inturn this destroys the turbo as it is working overtime trying to achieve its boost pressure which it cannot as it leaks from the split inlet manifold...!!

this has happened 5 times now and the vovo dealer just replaces the faulty parts...!! however there is obviously an underlyng issue...!

Has anyone had similar problems with faulty inlet manifolds and turbos on these engine..??

any advice greatly appriechated thanks in advance..

A warm welcome to the forum. I'm hoping that the likes of VolvoPaul and Spannerman see this post, as they can probably answer your question.

I have never come across this problem, but there is obviously an underlying problem. Do you have the correct airfilter as these were modified from round to square, then I'd want an engineer onboard with a Vodia in 'Live Data 'mode to read off boost pressure via the boost sensor and to check if the VNT valve is working correctly which adjusts the boost from the turbo.
Manifolds never replaced, one or two turbos yes, but these are generally reliable on these engines.

Hi,

I have the same engines, around 250 hrs ant trouble free so far. Spannerman, what do you mean that they changed the airfilters from round to square. I have the same model that is offered on Marine Parts can not see a modification (Round bottom square top)?

Are you saying there is an updated version on the market?

Thanks!

Thats one of the newer types so its OK, the original was a round drum, then they went to your type or a square one.
