Anyone Recognise This Engine?

[dcc 855]

put engine in the car and see if it works. #winning.

Thanks theo! I've just bought a compression test kit for £10 on the bay and I already have the pistol/gauge and compressor, so I will give it a go!

 

And it saves moving an engine about!

 

Think I will also need a box key to run up the pipe to be able to tighten the pipe in, in the spark plug hole.

 

I'm hoping some of you on here can help me find TDC!

[Anthony 1,003]

Is it a compression tester or a leak down tester you've bought? Two quite different things.

 

A compression tester doesn't need TDC - just the engine to be turned over at speed on the starter motor (which in turn needs the gearbox bolting on)

 

A leak-down tester needs the piston to be at TDC(ish) and the cams in a position where the valves are closed - a screw driver or similar down the spark plug is accurate enough for this as it doesn't have to be exact like it is for timing up camshafts for example.

I am not sure what is a box key but i am sure make it work!

 

For the TDC..put a screwdriver in spark hole of the cylinder you want to check..turn the crank..and when the driver reaches the highest point before start to going down,this is the one..if i am wrong,someone can correct me:)

Antony..he bought a compression tester and he ll use to make a DIY leak down tester:)

Anthony, as Theo's link, the compression test pipe can be used with a tyre gauge/compressor to get air in to head.

 

I'm not expecting a great deal of accuracy, but hope to be able to determine if "a lot" of air comes out exhaust, inlet, or dip stick, or not.

[dobboy 231 2 Cars]

Theo, re. Box key. How else could I tighten the pipe sufficiently on a 6 engine?

 

I.e you can't use a spanner....and the pipe will stop me using spark plug socket?

 

Unless you can think of another way?

 

I thought if I run a box key up the pipe before its attached to hand set, I could then slip it over the nut and tighten the pipe into spark plug hole?

 

Also, do you think it will be a case of watching the pressure build up like a tyre, and then slow right down? Then I should try locate the air from manifolds etc?

[theo-mi16-gr 4]

This is definitely a good way to tighter up the adapter if the rubber seal by its own isnt enough!

 

You dont watch the pressure building up as when flating a tyre.It is instant.This is why i would recomment to use the adjuster of your compressor.Going from low up to ie 100psi.And then read the gauge at pistol.This is your leakage.All this time the trigger of pistol has to be pressed of course.All this time you can locate the air at manifolds,coolant bottle,oil filler.

Most fords use the same size spark plug as Pug's, they are just longer reach normally

[theo-mi16-gr 4]

Miles: When he suggests the replacement of rings no matter the mileage, i wonder if is his setup really the problem...

Big mistake on these, the bores rarely hone to suit

[theo-mi16-gr 4]

Then even more possible for a mistake if not familiar with pugs.And no reason for changing them without testing the engine first in any way..

Just put it in the car and run it instead of wasting your time and money on tests you don't need. Put a new belt and pump on

Hi jazz,,,,, i hear what your saying and a couple of mechanics i know say the same, but you're also mechanic and changing an engine is probably your bread and butter.

 

You sold me the engine and you couldn't tell me anything about it.... it didn't look the prettiest on the outside, so I err on the side of caution as to what the inside's like.

 

Maybe unlike your profession, in my profession, if it looks good on the outside/maintained, the chances are it's good on the inside.

 

If its a bag of nails will you come and take it back out and put it back in for me? or would you rather i spent a couple of quid making sure (within financial restraints) thats it's good? (before i wreck a perfectly good car)

[theo-mi16-gr 4]

dobboy +1 !

[309jazzpanda 41]

just because an engine doesn't look pretty doesn't make it a bad one but I see where you are coming from and understand the caution you are taking.

[dobboy 231 2 Cars]

Jazz, no. I asked you if you knew if the cambelt had been done recently, you didn't know and advised changing it and the water pump..... Which I have bought.

 

Regarding wrecking my car, at the moment my car has no issues at all, and I'd like to keep it that way.

 

You seen what the engine and loom looked like yourself, surely you understand why I want it checked out by someone who jnows what they're doung before it goes in.

[Miles 331 1 Cars]

5 minutes of a test can save allot of time, Just done it on a Mi 16 engine which supposed to of had a rebuild only to find 6 valves where leaking, so head off again out of the car takes minutes and not hours, It's a test I do on all engine's as in the long term for paying customers can save them a fair few ££

[theo-mi16-gr 4]

Miles: Can save them(us) more than few quids! And who can disagree with you? only the mechanics who dont know the test..or avoid it for obvious reasons:)

[309jazzpanda 41]

Its not a difficult test to do as dobboy has proven in making his own test kit. I'm not saying you are wrong or in anyway bad mouthing what you want to do, everyone works differently and you are well to carry out what you feel needs doing. No hard feelings, I just don't want people to think I have sold you a lemon when I haven't

[dobboy 231 2 Cars]

Jazz no probs, I just want a bit of piece of mind without breaking the bank, and I would rather know if something was untoward before it goes in, so I can get it fixed.

 

Nobody's implying you sold me a lemon, people are just advising that it should be tested due to the lack of info available on it.

 

Hopefully for me the test shows it to be tip top.

 

Regards.

[309jazzpanda 41]

Have you finished making a tester?

[dobboy 231 2 Cars]

The parts haven't arrived yet. But if for any reason the kit can't be butchered to work I can get the test done by Ecosse, which is fairly local.

[dobboy 231 2 Cars]

That's the compression tester arrived and it looks as though this will be easier than I thought. The part of the kit with the valve won't be needed, i can blow right through the pipe with the spark plug connections, so it looks like I should be able to connect the spark plug pipe right in to my tyre gauge/pistol.

 

I was thinking, regarding my shortage of calibration of either my compressor gauge or my tyre pistol gauge. If I could fit a tyre valve to this pipe, put the engine in back of my van, went to local BP garage, set their machine at say 90psi, then blew into into a cylinder, I would be able to see on their gauge what the cylinder was holding to?

 

And to add to that, I should be collecting another gti6 engine this week, c/w all ancillaries and box.

[theo-mi16-gr 4]

Is there a specific reason you prefer your locan Bp garage? I dont think there is actually any kind of calibration.At garage you have to know their compressor psi too.
