DIY Boost leak tester guide

[trebormint]

Can this be used from the intercooler outlet back to the turbo on a TDI?

Can any damage be done to the turbo?

And/or is it safe to go from air inlet (after MAF) into the engine?

 

[james walker]

test pre turbo, or through charge pipes. pre turbo no more than 10psi really

I have leak somewhere between turbo out to intercooler in. I was hoping to use this leak tester backwards, i.e. from intercooler outlet back to the turbo.

Other option as you say is from tip to engine - would this be the safer bet?

 

[james walker]

why not use from turbo out at the charge pipe..... this then flows through the cooler??

Because I want to test the turbo to sfs turbo pipe seal.

 

[james walker]

youll have to help me out here.... does your tip go to the turbo, then turbo to intercooler then intercooler to throttle body??

sfs pipe being the tip????

if so then leak test through the tip, no need to do it backwards, just connect to the tip inlet. use no more than what you boost, a little less will see leaks.

if the sfs hose your on about is between the turbo and charge pipe, then again test through the tip.

dont test backwards through the turbo...not good

Right... only just got in so I could not take the silicon reducer off my FMIC to mock up a pic for you for the standard SMIC. But you will need to buy a slicon recuder 63-51 (e.g. http://cgi.ebay.co.uk/63mm-51mm-BLACK-SILICONE-HOSE-REDUCER-VENAIR-SILICON-/310221718321) and connect it to the end of metal intercooler pipe that runs across the back of the cam cover.

If you look at my tester you can see that I have a rubber 63mm joiner with a 63mm end cap. I've drilled two holes in the end for the guage and air valve (both got off ebay). The end cap was couple of quid from the local plumbers shop.



I also got a pipe bung (19mm 3/4 inch) that cost a few pence to block the PCV outlet and used an off cut of 3/4" hose to connect it to the black plastic connector to the TIP.

Good work mate.

This makes ZERO sense to me, as James said(and he knows) test through the TIP, i posted pics earlier of the TIP based boost leak tester, its the same just with 80mm pipework for the LCR.

If you pressurise the system from TIP it will test all pipework, also i won't recommend going over 10psi max on the turbo test.

TIP into turbo, turbo through SFS turbo hose, pancake replacement pipe into intercooler. More custom pipework from intercooler to inlet manifold (no throttle body).

I think it will best I go through the tip.

thanks

The SFS turbo pipe replaces the standard red turbo pipe - comes in two parts - an alloy connector and silicone hose. Unfortunately the alloy connector supplied is not the best fit into the turbo. Further, there is a possibility of a leak if the silicone pipe is a not a tight seal on the connector!

I'll test from tip onwards at a max of 10psi.

cheers

 

[james walker]

right.... so you did mean the tip then.

 

[sambryant]

Yes he does mean the tip James lol just been Reading through the last few posts, talk about banging your head against a wall
James did u find a leak?

 

[trebormint]

right.... so you did mean the tip then.

I said all along - either through the TIP or back through the intercooler.....

Just wanted to know if safe to go back through turbo - obviously not

And if safe to go through TIP - obviously yes but to a max of 10 psi

I thought I was making sense - obvioulsy not lol .

how do i go about blocking my pcv on a 180 lc

 

[james walker]

pull it out of the tip and block the pipe off with something, also block the tip inlet you pull the pipe from

 

[stef cupra]

can anyone show me a picture of the pcv on a 180 lc

Find the Y-shaped breather hose on the passenger side of your rocker cover

Follow it down to the front of the block and you will see all these hoses. The PCV is housed in the T-section, as labelled on the photo.

 

[stef cupra]

so i need to block that to do the boost leak test?
