Advanced Motorsport, is what Dan is operating under out of there. He is still affiliated with Jikan for parts I believe but as haven't spoken to him in over 2 months cant confirm that...as have been very poorly... just felt a bit better so thought I'd pop on and have a look see whats been going on.......!!!!!!!!! by the way this is Sam not Greg forgot to change the user login id....sorry.....

Only just read this ............ Just like to say Thank you.

And it has not got the graphics on it yet or the new wheels or the new glass or the new engine or the new gearbox or the new fuel system or the new seats or the new dash or the new gauges or the new ECU in fact it's still just a shell and boy am I really P***ed off that I am not going to be at Jap Show. By the way Si I think your car looks real mean:d

Just to add that the NA pump does not have the crank sensor hole fixing.

No it is not a wind up. Brand new from PHR with I might add the new casting pump housing, put it on the car and hey presto leaking from the same hairline crack running down the reilef valve housing as the other new pumps. Really strange sight to see as the oil appears as a line at the bottom and then works it's way up to the bolt then pours out. Shame I did not have a video camara as it is the first time I have ever seen oil go up.

Yes jamie you are correct, the spring was always in place. OK food for thought, on Jamies car there is no drip on idle or when you rev the car standing still even up to 4k, the seal only starts to pass oil once the engine is under load and has had some boost put through it. As stated the engine is a brand new short block from Toyota and was put together with new HKS 2mm head gasket and jamie's old head which has done less than 5000 miles since his rebuild. So after two new seals we still have the leak.

Chris, this engine is a brand new short block from Toyota hence the crank is factory. Strange thing is that we have not had this problem with any of the bottom end rebuilds we have done. The company that we use for our crank work also do work for most of the race teams that are on the estate and noe of them have had any problems. As to the seal and instaling it it can only go on one way unless the person putting it on is a complete idiot ( We are not) And yes the new seal'sl do have the rotation arrow same as the old ones.

Thanks for that.

Hi Chris, we used an Absolute Digimatic vernier caliper to do the mesurements.

Chris, Can you enlighten us with how you do that trick with the spring please.

Just a quick change to my post about the difference between the old and new pumps: I said the the left hand side of the new pumps had an extra fitting, it is in fact the right hand side. Just goes to show how left and right can get mixed up whilst upside down.

Chris in no way would I ask you to butt out as I value your input on this subject and feel that some light may be shed and other people will benifit from the information. On to the pump and seal sizes. Old Pump and Seal. The OD of the seal is: 63.02mm The Od of the pump recess is: 62.73mm New Pump and Seal. The Od on the seal is 63.29mm The OD on the pump recess is: 63.05mm Quite intresting the results above although there is bound to be some expansion on the old seal due to heat, which means that the new seals are slightly bigger.

Thanks Chris we will get Jamie to give the car a run with the new seal in and the oil cap off once we have put in the new seal. I will messure the OD on the pump and the seal once they are removed and post the results.

I never rise normally to comments made like this but enough is enough: " Is there any correlation between the companies carrying out the work and the failure rates?" Why not just come out and say Turbofit are not doing it right. "Are things being installed properly?" We have been doing this for a long time and we only use the right parts and tools supplied by Toyota. These oil seal and pump problems have only just started in the last couple of months and then only with the new parts supplied by Toyota, I have lost count of the number of front seals and oil pumps we have replaced in the past but there have been quite a few and all with no problems. Perhaps you might like to try and be consturctive for a change and not desturctive.

Hi Chris, sorry I do not have any pictures of the new pumps as the two failed units were sent back to Toyota for inspection. There is however an easy way to tell if you have one of the new pump case's, as you look at the pump look to the top left hand side of the pump on the old pump case the top left hand edge is smooth, on the new pump case there is now an extra threaded hole at the top left hand side. We can only assume that this new fixing point has been added for the engine in the Lexus series. Also we have recently put in a brand new 2JZGTE short block from Toyota and noticed that there is now extra engine mounting points on the block again we assume this must be for the Lexus series. As for Jamie Ps problem the new pump that was fitted to his engine failed and was replaced with an old but known oil pump, a new oil seal was fitted on start up and idle there were no signs of any leaks however after a drive oil was leaking from the seal, after a front end strip down it was found that the seal had moved forward, using the Tool supplied by Toyota the seal was put back in place and the front put back together again. On start up and idle again on leaks but after a short drive the leak was back, at 8.30pm we decided to give up for the evening and await the delivery of some new front seals in the morning at which time we will strip the front down again and do a very close inspection. Just a note: We have now heard back from Toyota and to be honest it is not a very good response. In a nutshell they have admitted that they are now having the oil pumps made by another manufacture but at this time cannot do anything other than replace the pump on warrantie, whilst this is no more than we are entitled to under the consumer act I cant say that at the moment I would take a new pump as without a way to test them off the car it is a shit pile of work to put it on and find the same problem. At this point in time we are down by 5K in parts and labor with no way of getting any of this back. The public relations officer at Toyota was quite shocked at the tale but said that his hands were tied and unless there were more returns that there was no more he could do. Shit month really:(
