Scott Posted August 6, 2011 Share Posted August 6, 2011 I'm replacing the springs & retainers in my spare head with BC items. I got everything out absolutely no bother but I'm having a bit of bother getting them back in (2 in an hour ) I've managed to find the tool that Ian recommended and have ordered it. However, I can't for the life of me see how it works. The following image isn't the exact same one but it is a very similar design and it would appear the OP used it to create the how to on MKIV.com. How does the tool manage to get the keepers in without fouling on the top of the valve stem? All I can imagine is the tip of the tool hitting the top of the stem and not allowing the spring, retainer and keepers to move down. Any insight would be greatly appreciated Quote Link to comment Share on other sites More sharing options...
bigbloodyturbo Posted August 6, 2011 Share Posted August 6, 2011 I 'think' the idea is that the outer white parts pushed the retainer down and the inner pointy bit is magnetic allowing the collets to stick to it. As you allow the spring to come back up the collets get trapped between the retainer and the stem as they should but allowing the centre section to carry on being removed.

Chris Wilson Posted August 6, 2011 Share Posted August 6, 2011 Yes, that's about it, it's spring loaded, but be careful, the little devils called collets will leap out sometimes, either into an obscure corner of the garage, or, if ALL the oil drains and holes down into the sump of the engine aren't blocked with tissue, Sod's Law states one will go down there.... The tool looks like it can't work, but it does. You need to turn to OD down on Snap On ones, otherwise they'll mark up the tappet bores in the head. Get some spare collets...

The head is on the bench so no need to worry about losing bits thankfully. Is the centre part spring loaded Chris? I can't see how the retainer will be moved down without pushing the valve down as well. Quote Link to comment Share on other sites More sharing options...
Kirk Posted August 6, 2011 Share Posted August 6, 2011 An easier way to do it is get an old socket that's slightly smaller than the retainer, an extension bar and give the retainer a smack using a hammer, not to hard though.

Chris Wilson Posted August 6, 2011 Share Posted August 6, 2011 Yes, spring loaded, have a look at my answer mate.... If I had a web cam I could demo mine, it'll all become clear once you have the tool in your hand, as the bishop said to the actress Quote Link to comment Share on other sites More sharing options...

dude Posted August 7, 2011 Share Posted August 7, 2011 Horrible things, why cant you use a proper spring compressor??? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 7, 2011 Share Posted August 7, 2011 Yes, I was wondering why you need to use this gadget, if the head is off the car? A proper spring compressor is what you need. Probably cheaper than the Snap On gizmo, as well. Quote Link to comment Share on other sites More sharing options...

I'll catch you later in the week as i get a bit stressed with all the mess etc and with the plant going we cant hear the phone anyway, same numbers dude.

I did look into those but had no idea which ones to get. There are so many variations that I decided the tried and trusted method would be just fine. Also means that I can do the job on the car in the future should I have the need. Are the spring compressors suitable for the 2JZ the C-Clamps?

Are the spring compressors suitable for the 2JZ the C-Clamps? I had to buy a new valve spring compressor as my old one wouldn't fit. The one below is almost the same as mine and it works perfect. http://www.justoffbase.co.uk/Valve-Spring-Compressor-Multi-Valve-Sealey-VS154 -edit- infact, looking at it, i tihnk it is mine actually. I just got it from my local motor factor. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted August 7, 2011 Share Posted August 7, 2011 Using the Snap On tool with the head off the car will be a nightmare, how will you hold the valve heads up in the chambers? I think you should get the proper tool! Quote Link to comment Share on other sites More sharing options...
