#4 Cylinder problem-Any 3.5L vtec work?

Hello, New to ridgeline and forum. I have been lurking for a couple of weeks. I believe the 06 ridge i just picked up is beginning the dreaded 4 cylinder problem. It has 155k on it. My question is, when they begin to tear it down and "diagnose" the problem, if it does come to a new engine-will any 3.5L vtec from an odyssey or pilot work? There are a lot of those engine out there but only a few for the ridge at considerably higher costs. Should i just do a short block?

Thanks for the potential guidance!

Hi - I'm looking to buy a 2006 RTL with 135,000 miles. I'm concerned about this issue and was wondering what your manufacture date is?

The one I'm looking at is 08/05.

will any 3.5L vtec from an odyssey or pilot work?
No, any as in "all" will not work, but some might work. Beginning in that era, some Honda 3.5s got the Variable Cylinder Management system which the Ridgeline never received. It's generally not something you want to have in my opinion, and the Ridgeline computer probably isn't set up for it anyway.

Wikipedia has a list of applications of VCM:

2003 Honda Inspire
2005-2007 Honda Accord Hybrid (JNA1)
2005+ Honda Odyssey (USDM) EX-L and Touring Models only (J35)
2006+ Honda Pilot 2WD Models only (J35)
2008-2009 Honda Accord except EX-L V6 6MT Coupe
2010-2012 Honda Accord V6 (except EX-L V6 6MT Coupe)
2013+ Honda Accord V6 (except EX-L V6 6MT Coupe)
2009+ Honda Pilot (all models)
2013 Honda Accord V6 (except 6MT coupe) *VCM operation is 3- or 6-cylinder mode, no longer 3, 4, 6-cylinder operation.[1]
2011-2014 Honda Odyssey (USDM) V6
2013 Acura RDX V6
2013 Acura RLX *3 or 6 cylinder mode
2014 Acura MDX *3 or 6 cylinder mode
2015 Acura RLX Sport Hybrid *3 or 6 cylinder mode

In general, it looks like 2006+ FWD Pilots had it, 2009+ all Pilots had it, 2005-2010 Odyssey EX-L and Touring had it, and 2011+ all Odysseys had it (plus various Accord models throughout).

You'd probably be safest to get a re-manufactured short block, if it does come to that.
