Need new head. Your ideas?

Early '99 V10, about 160K miles.
Blew a plug on the road and mechanic says it already had some kind of insert work done and there was not enough material left to put any known insert in.
They see no option other than a replacement head. We cobbled together a temporary plug to get us home. I will be pulling head to check things out myself. Since I will have it home, I will be doing all work from this point forward. Lots of experience, no concerns there. I have several months to play with it, but somewhat limited $$$. No Cummins swap...

So.... If heads are buggered by bad insert job by PO, I might as well replace both heads. As a min, I'll use '03 heads. Can I fit 3V and get more power bump? Use same intake and exhausts?
Or with 160K miles, should I just find and swap in a complete low mileage engine?
Any thoughts appreciated.

I'd stick with the 03-04 heads you'll gain some power due to the PI head update

the 3v heads will bolt up, the thing is that it has an adjustable cam phaser up to 60* total which is controlled by the pcm with oil via a solenoid in the valve cover. You can "jam" the pahser but you'd be loosing gains over the power band, it's not all that bad sence you now have a 3v cylinder head on your engine and efficency took a turn for the better but you'd be a ginnea pig intell you degree the cam's, and did some dyno tunning.

As for the intake your stuck with the same dellema it's volume is veriable and controlled via the pcm, if your heart is set on 3V then a 3V pcm would be a wise choice.

Do you plan on keeping the truck long enough to justify the cost of another motor installed? if yes drop in a low klm motor

Thanks for the input! There were quite a few more changes than I thought.

I have a line on an '06 from a class A motorhome with 6K miles (rear end wreck). Now I'm researching if that would be 2V or 3V... Would definitely try to get PCM and everything else I can grab.

A Class A should be an E-series chassis, which would be the 2-valve engine.

I would check the intake ports and make sure they are the same between the '99 non-PI head and the '00-up 2-valve PI head.

Also, you are in for some trouble because the '99 PCM will want an EGR - and you'd have to keep the EGR and it's plumbing. But with PI heads, the PCM might not run "ideal".

You might be headed for a custom tune, or a 2000 PCM.

3-valve, forget it. Without the variable plenum stuff in the PCM, you would hobble the motor more than just running 2-valve heads.

The V10 is not equipped with VCT and the variable runners in the intake default to open when not powered up.
Which means you may run the 3 valve with an appropriate 2 valve ECU.

your right about the VCT it's only on the modular v8's. While I was digging in deeper there might be some other problems with the swap, the 2v blocks are 90* while the 3v is 60* which means when you go to install the intake on the heads your going to have a problem with the flanges lining up evenly, the only ways I see of fixing the problem is by milling, spacers, modifing the 2v intake, mind you this three ideas create there own problems in some way. Also you might have to use the balancing shaft for the 2v on the 3v heads weither or not it will fit I'am not sure but with a machine shop anything is possible

Also there might be something about the c.o.p's and spark plugs I'll have to check it out.

conerning the veriable intake if you leave it in default mode your going to have holes in the power band which is unpleasent for stop and go situations.

If some ones concerned about CC here they are with firring order and bore diameter

1999 Non-pi 2v- 51.6/52.6cc 1-6-5-10-2-7-3-8-4-9 BD-3.5517
2000 pi 2v- 51.6/52.6cc 1-6-5-10-2-7-3-8-4-9 BD-3.5517
2007 3v- 48.1/51.1cc 1-6-5-10-2-7-3-8-4-9 BD-3.5517

I have a similar problem as mwsf250, I blew number 8 plug out a month ago and did an insert as well. I drove it Jed Clampet style home about 12 miles thinking I blew the oxy.senser. I was successful with the insert; but now when I start up in the morning I get a puff of blue smoke. Not always does it puff smoke, about 1 in three times when starting first thing it will. I'm wondering if I damaged valve guides or seals? Anyway, can one just swap in a later model v10, say a 05 of newer from a wreak?

plug thread repair

Just a thought - - You might check out the BigSert insert that is made by TimeSert. It is made specifically for cases where a previous insert has blown. I THINK the literature says if you can clean up the old hole to no more than .640 then you can use this insert. That's over 5/8 inch - - pretty good sized. Would sure beat replacing a head - - or heads - - in terms of money and effort.

This is the third recent post about a blown repair insert. Makes you wonder if all inserts are created equal?

if it's just when it start's and goes away then it is a leaking valve seal, mind you it could be rings on the way out, id reccomend a held compression check, if you find a cylinder thats losing comprssion over time add some oil to the cylinder via the spark plug hole and do the CR test again and if it holds the rings are the cause and if all the cylinders hold CR its a or many valve seals.

If it's not piston rings on the way out I wouldn't consider getting a new engine.

When I did the insert I tried to be careful not to drop aluminum into the cylinder. I greased the tap good and evan hooked a small hose to the shop vac to get any fallen debris out beyound the spark plug hole and into the head. If it turns out to be valve seals, can that be done with out pulling the head? The truck only has 60k and I hate the thought of tearing into it. Thanks

yes it can be doen with out removing the heads but you'll need some speacail tool to do it, valve spring compressor but not just any will work I'll see if I can find a pic of it. First thing you'll have to remvoe the valve cover then rotate the engine via the bolt on the hub. For example your working on cylinder #2 you'll have to turn the crankshaft in till both valves are closed aka TDC, you'll know when you achieved this when you see all preasure has been released by the cam followers on the valve tips. Once you see that you have achieved TDC and can not move onto removing the spark plug and filling it with compressed air next you remove the cam follower then the valve locks, springs,valve seal. *Do not forget to fill the cylinder with compressed air*

Wow, thanks a million. I now remember doing something similar to this 25 or 30 years ago on my 68 Mustang. I evan think I might be able to find that old spark plug air chuck at my dads house, although I think its for the old big plugs. Will I need a special tool for the valve seal as well? My memory of them on old engines (windsor or fe) was a mushroom style gromet pressed around the valve guide seat.

The 2V and 3V use the same 90 degree block angle.

Do you get the blue smoke only after you start the truck, run it for only a minute or two, shut it down, and then restart the next day?

Also, check your PCV system...
