Simple Turbocharged Zetec: Build Diary

Recommended Posts

On the cleaning front, it may be worth noting that especially if your working on a cast iron block that sort of rust can appear in minutes some keep oil, or wd40 or something on hand to protect it straight away otherwise you may have to do the whole thing again. You definately don't want that building up in the bores or similar areas.

It's been a while, so let's update..

 

 

So the intention was to use an escort rs turbo exhaust/turbo manifold on this engine. The original Escort front breather/baffle unit unfortunately fouls this manifold so the decision was made to block off the front breather and add one to the rear of the block.

 

This shows the front breather hole on the block with nothing in it. A core plug will be pressed into this.

This next photo shows the rear breather (upside-down photo). A hole was machined into the back of the block and the fitting was a press-fit into place.

This shows the breather port from the inside of the block. It wasn't the best method of doing it and peening over the edges over on the inside was about as good as it was going to get in this instance.

Now this is not the same photo.. you may notice a new hole has been drilled into the block...

But what is it for, you say?

 

 

Here is it with the oil squirter jet in place (which has been thoroughly cleaned out before with the block cleaning)..

And here's why..

A baffle!

 

The last thing you want is to accelerate in your new turbocharged monster and half the oil exit the engine via the breather... so adding a baffle is very important.. this is just a crude design and would be changed if found to not be adequate.. I didn't have any track day plans so was happy with the design for now..

 

Not finished though.. and this is my favourite photo of the whole build..

A small blob of weld on the right-hand bolt.. don't need that baffle coming loose in the engine!

 

 

 

The next chapter will talk about the actual build up of the rotating assembly....

The oil squirters have a spring-loaded ball bearing in them so they only actuate when there's a sufficient amount of force to open the valve, then the amount they spray depends on engine speed and oil temp/viscosity.

Just another question if you don't mind :)

 

The blanking plate for the breather. would these do : http://www.ebay.co.uk/itm/110960290645?ssP...984.m1436.l2649

 

Or is it better to use a triangular piece of metal with a gasket that bolts on?

 

Thanks :cheers:
