VTEC unlimited warranty

[topless_mx5]

I am possibly looking at buying a 2.2 Prelude, and I came across this ad: http://cgi.ebay.co.uk/1998-HONDA-PRELUDE-2-2-VTI-R...

The seller has stated: "responds to being revved due to the nature of the Vtec system, which is covered by Hondas unlimited mile warranty down to their inherant reliabilty."

Is this true? Is there an unlimited miles warranty on the VTEC system, or is he chatting sh!t?

[priteshm]

chatting sh(t mate.

Maximum Honda warranty from new is 3yrs/90,000 miles.

'tis bks but Honda have never had a Vtec claim under warranty

[10 Pence Short]

There have been plenty of VTEC faults and plenty of engine failures. What they haven't had is failures of an engine attributable to VTECs presence.

I work for Honda U.k Swindon and there is no such thing a imfinty warranty on Vtec Systems but they never go wrong

That's also not true!
The F20C in the S2000 has had vtec failures.
Lack of oil to the central journal of the vtec cam causes it to seize, breaking the timing gear introducing valves to pistons!

There are also a few Type R's over on Civinfo that have gone pop.

I would imagine an awful lot of the truth in the general statement relies on interpretation. Either way, there is an awful lot of bullsh*t spouted about VTEC engines from people on both sides.

I have a 1997 2.2 vtec auto tiptronic sss BB6 done 125000 kilometers (85k miles?)
The ignition switch failed and the Auto box now has a "rattle" is park and neutral select.
I have found out that Honda had a recall on this model for over 7 years because of these potential failures.
When I tried to get them to confirm just after I bought the car (within the 7 year timimg) they told me that the model I have is made in Japan and has never had a re-call or any failures--I rest my case.
Having said that, the car and engine is absolutely brilliant but now for sale due to new car.

Opps! Sorry. I just looked at the date the original message was posted!!

I thought lack of oil would prevent activation of VTEC (i.e. locking of the lobes to the 'central' VTEC-cam to give the extra lift), and therefore would be fail-safe?!?

(Not that oil-starvation is ever 'safe', but you know what I mean.)

[Carfiend]

Depends if the oil pressure is high enough to allow VTEC to run but you get starvation under heavy cornering I expect.

[s.m.h.]

Its oil pressure that keeps the Vtec engaged. It would have to be starvation to individual bearings not the head itself. If the oil pressure drops vtec wil dis-engage.

Exactly what part is "the Vtec cam"?


There are 2 camshafts with 3 lobes per pair of valves. No specific vtec cam. Oil pressure engages pins that lock the cam followers together utilising the 3rd lobe. Technically camshaft failure isn't vtec failure....

Each lobe, technically speaking, is a 'cam' - hence the 3rd lobe for each pair of valves is the VTEC cam.

...and I know how VTEC works, hence my first post.

It was referring to an earlier post saying the vtec cam seizes.Unless its the follower seizing or one of the cam journals running dry. I apologise if it seems Im telling you something you already know!

Sorry SMH - my mistake. I was confused a little by Mikey's post too.

B18 series engine is the one to have. Although all good engines the others seem to use oil, hence Vtec failure. Keep the oil at the mark and You'll have no problems.
