Time for a rebuild?
« on: 13:31, Mon 18 February 2013 »
Hello all,

I am not a frequent poster on the forum, but after a little bit of advice pleeeeaaassseeee.....  

Could be a sad time for my R5 Turbo.

A crack in the rad about 6 months ago, obviously made me put a new one on.  Car didn't overheat.  As the summer is coming I am putting her back on the road, but now there is a leak from the head out the side of the head.  Looks the sealant has split.  Would people think that the head has cracked?

I know very little about the R5 a part from the work I have done on her over the last 3 years....  It's an H reg by the way....

Any suggestions, positive or otherwise?

Thanks all for reading my woes.

I will try and get a picture tomorrow, but on the right hand side of the block as you face car. Think that is where the blanking plate is...

There is a blanking plate there, six bolts hold it on IIRC.

You might be lucky and it just needs a new gasket (or sealant works just as well to be honest...) but be carefull with the bolts though, the threads have a nasty habit of messing up.

Im a little unsure how to put a picture on here, but I can confirm that it is the blanking plate side of the engine.  Therefore do we think that it could just be the gasket?
What is this gasket called, so that I can get another one.  Thanks Again....

It's this item here.

For a quick fix (...or a more permanent one in my case  :lol: ) silicone sealant works just as well.

Although, not 100% relevant to my posts above, could someone have a look at these photos

http://s1308.beta.photobucket.com/user/ ... 8990450953

There are three on here, if I have uploaded correctly, and tell me what the circular part is.  Its all located by the back of the block, below the carb.

Thanks All.....

It looks like your pointing at the inlet manifold?

There are identical circles at each end of the inlet manifold. They don't do anything as far as I know, I think there just cast that way or they might be plugged. There is coolant flowing through the inlet manifold if you still use the standard setup.

Would it therefore be fair to say, that if water is leaking from here, then this is not a good sign then?

They must be plugged there then.

You don't 'need' the coolant running through there, I personally haven't got the coolant running through the inlet manifold.

You could either attempt to re seal the plug, replace the inlet manifold or just bypass the coolant.

At least this does not seem as bad as I thought.

I will see if I can find a bung (sure the original one must be somewhere)

Failing that is there a guide on redirecting the cooling?  What are the pros and cons of this?

Thanks
