PRV B27 or 228 wanted

edolson · 07-11-2012, 02:11 PM

I am still looking for a good B27 or b28 prv from the late seventies, early eighties in good condition... sometimes those with a bertone want to upgrade and they have a perfectly good used enging... Any leads?

If you're messing with an engine don't bother with the B27. B28 fixed many of the problems that plague the B27 (B280 reportedly fixed almost all of the remaining ones).

B-28 is the same engine with 91mm boresize compared to 87mm bore of the B-27. B-28 got Lambda. Same oiling issue which was mostly due to Volvo saying "Change that oil every 7500 miles whether it needs it or not" and it got changed every other year...... The tiny little holes in the rocker arms got plugged up due to lubricants being what they were back then. Cams died. K-Jet is what it is.

B-280...... Nice runner. Even-firing pulses for a smooth idle. Oil is pooled under the cam so the rocker arms getting plugged up is not the end of the world. They obviously still need oil changes. Synthetics are it's friend + good quality coolant.

OP...... What are you putting a B-28 into? A period-correct car? A DeLorean? A project that requires an original engine?

With more effort one can be made that looks stock with more displacement, a smooth idle and will have internals that are just-so for a turbo should you wish for that in the future...

I'm also looking for a complete nice running B-28.... Coming up with nothing.

JohnLane ,you seemed to be the go to guy for PVR motors.I have 2 Bertones,all stock a 79 and 81.I have not had any issues with them or the previous 80 coupe that I parted out.My question to you is have you heard of a mod to these motors that helps the oiling issues to the cam? I seemed to remember talking to a volvo tech many years ago who mentioned a TSB for the PVR that the dealer would do when these cars came in for service and the customers were complaining about excessive engine noise[cam wearTIA

Yeah I'm the sick one.......

Oiling fun.... Ready for the biggest thing you can do for it that will keep it alive?

It is a really high-tech fancy difficult thing that we didn't have back in the mid '70s when this engine came out.....

Here it comes.....

Synthetic engine oil. 10/30 weight that gets changed as it gets to changing color. Keep the inside of that engine sparkling clean with it and you'll never ever have any issues with oiling. There are a number of good choices on the market today. I've seen excellent results with Mobil 1. Another benefit.... Zero wear.

Do also use a really good quality coolant such as Toyota's Red coolant or Honda's blue stuff and mix it with distilled water. Change it on time. Your radiator will never plug up and the engine won't be slowly digested via the cooling passages. These good coolants we also did not have way back when.

Good advice! So no info on said TSB for PVRs that you've heard of? I may have to do a search for the Volvo tech who mentioned this to me.I kinda remeber him saying some type of plate was inserted/or welded in under the cams to keep the oil splashing around to keep stuff better lubed.Does this make sense?

JohnLane · 07-11-2012, 10:20 PM

In all of them I've seen..... No 'added in plate' or any such thing......

I used to pull out all the rocker arms, drill the holes bigger and drill the holes in the end of the rocker shafts bigger where the oil comes up from the bottom end. Yup; more oil on the camlobes and an oil light that may wink at you at idle on a hot day during the summer. I didn't have cams die before.... had no cams die after.... Wonder why?

Reality: Synthetic lubricants and engine cleanliness are the holy grail for keeping it healthy.
