I am about to replace my VP2003 head, problems say the fitter withe the old one.
Any tips from others who have done the same that would help and I should know about this model will be most welcome
 
What are you going to replace it with? If it's a VP exchange head, it's £2.5K which would be a good contribution to a new engine.
 
Its a properly reconditioned head, seen lots of photographs and spoken with the seller, who has a 100% record on ebay, so pretty sure it is as described.
Would agree if £2.5 would be a fair deposit on ne.
 
I do recall you advised me on a high output alternator, some years ago for a Perkins 4108.
Is there anything similar suitable for a VP2003, as explained this is a new engine in my experience.

I haven't seen that on eBay, can you post a link?

What exactly is the problem with the original head?

The fitter identified water passing up past the injectors, which I understand are set in copper inserts.
He checked everything else all working well, starts no problem.
I have since done a 30 miles trip on engine only and after some 15 miles a white smoke, more misty was emitting from the exhaust, no effect on running, at least to my ear.
I rang the fitter who confirmed this was as he had found, moisture getting into the cylinders resulting in the white smoke or steam.
Apparently changing or renewing the inserts quite a job.

You need a new fitter! The copper sleeves into which the injectors fit are sealed by O-rings. If you have the correct tools (Volvo Penta dealers have them) it's an easy job.
 
Best you take an overnight bag. You are being led so far up the garden path you will need it. Have you checked the exhaust elbow for blockage? Injector inserts will cost a fraction of that price if needed

Iam going from memory on his verdict, you may well be correct. would the white smoke be a symptom of his diagnosis
 
Yes, get the head to an engine machine shop or volvo penta dealer. An engine machine shop will be well used to changing copper sleeves, some volvo engines used in lorries have the same set up (the sleeves aren't the same part though) so they will have the tools.
Can you see any water building up or seeping from around the injectors at the top of the cylinder head?
Is the engine raw or fresh water cooled?
Unless he has x Ray vision he won't know if there is water leaking from the sleeves into the cylinder when it's running. I have seen water being ejected out the top of the sleeves from cylinder pressure when they are gone.
There are other causes of the steam from the exhaust.

White smoke is a symptom of unburnt fuel caused by insufficient combustion chamber temperature. Can be confused with water vapour from water in the combustion tract.

His inspection said all it fine otherwise so I have not checked the elbow.
Is it the case that water can and does pass the injectors causing what I now believe to be steam from the exhaust.
My previous has a perkins 4108 that i serviced and maintained for a very long time.
The VP is new to me, any advice or details a big help

Common problem blocked exhaust elbow causing lack of flow resulting in "steam" emitting from exhaust. In my experience if the injector sleeves leak, they leak to atmosphere, not into the combustion space.

I have not looked for any water seeping for myself. All this as done in my absence due to the current restrictions.
The engine is raw water cooled. I am trying to recall his full diagnosis from several weeks ago, he has no financial interest in selling me a replacement head hich I found quite independently of him.
However is does appear he may have mislead me, I do not think intentionally, his charges were very reasonable.
I am on the boat now and it would be fine to run it and check, or is it too late for you to do so now, orperhaps tomorrow morning.
I will pay particular attention to any seeping.
Perhaps before I attempt to fit the conditioned head I should get mine checked by a VP dealer and have the copper sleeves changed.
The replacement head is fully refundable so no problems doing so.

I will check the elbow for blockage and get back to you.
 
If he said 'water passing up through the injector sleeves' that would mean water is being ejected out the top of the sleeves, you should be able to see that around the injectors when the engine is running. So check for this, he could be correct about the sleeves if this is the case. Water can dribble from the bottom of the sleeves when cylinder is on the induction stroke and cause smoke/steam. But there are other causes that need rulled out first before removing the head. As has been said check that exhaust elbow first.
