Is it going to be expensive?? Ouch....

Need your help guys ref my Speed 6. Has done 27K and was rebuilt (not by me) at 21K 4 years ago (TVR Power)

So I am out for a hoon with my brother showing him the delights of TVR ownership. Did about 150 miles around the fantastic A roads in Northern Italy. Took it up to 5-6K rpm a few times to show him what it is made of (made sure it was correctly warmed 1st)

On the way back home, I performed an overtake in 3rd and took it up to about 5Krpm. Immediately after the top end started to go rattly - almost like a click click sound. ALmost inaudible below 2krpm, but noise increased with revs about this range. Same whether in or out of gear

I was absolutely gutted and pulled over to have a better look. No drop in oil pressure (around 35psi), no red oil warning light, no drop in performance. Checked oil level, half full

Nursed it home for 5 miles and sound continued, keeping revs below 2K rpm. Then decided to blip the throttle and the ticking/clicking suddenly cleared!!!!

NOw, can I be relieved or is the engine needing a rebuild. It almost sounded as though a valve was stuck?? Could it be that the oil was not getting round top end momentarily and got something to stick? Whatever it was, it has now cleared but I am now very dubious and concerned. Does it sound like another rebuild or should I just make sure I keep oil level at full level at all times??

Would really appreciate your ideas/input on the causes and my next move!!

Cheers all

The obvious thing is to not drive it, get a look at the top end and see if any damage?

[sshenton1975]

Sorry for being a bit dim, but does that just involve removing rocker cover and having a look? What would I be looking for exactly??

Cheers

I am no expert - why dont you post on the Speed Six engine forum?

A compression test will show if any valves aren't seating correctly.

In bocca al lupo!

I would speak to the good people at STR8SIX, what they don't know about the Speed 6 isn't worth knowing. At the very least they will be able to tell you what to look for.

might not be the motor... you could of just blown the inside of a Cat out and its rattling around in there...if it does'nt rattly on idle or up to 2k id say it wasnt likly to be your motor.... if it was top end its more than likely make a real racket on tickover!!
