Some pictures. Here you can clearly see which piston was running w/ closed intake valve due to damage on cam Damage on piston from valve And cylinder scratches, honing should make it as new again

Thank you for the offer. I have already managed to get the F type. Head is separated from block and I am more and more worried what previous owner did to the engine. Two pistons have marks from the valves,all cylinders are scored (piston rings probably broken),rocker arms have only 2/3 wear pattern. I did found another free lashpad - this time in head. So the engine was running with 13 of them - 11 on valves, 1 in oil pan and 1 hidden somewhere in the head.

I finally found some time to take out the engine. I was surprised how easy this is! So much space in the engine bay. Because "the winter is coming" I will have more time so I decided to strip down the engine and give it a good care whilst it is out of the car. Hopefully, there will be no other surprises like before.

Sry, I did paste wrong link - it is edited now. Well, $13 in US, but to buy it in Europe £45.33 (http://www.amazon.co.uk/gp/product/B0002Q8TV4?keywords=Nissan%20Timing%20Chain%20Holding%20Tool%20for%201970%20to%201983%20Models&qid=1443556955&ref_=sr_1_1&sr=8-1) and that is really expensive. So I might go with the piece of wood.

I already have the book so I know what to expect. Thanks for all the advice. I might go the longer, but safer way. I will just need to fight my impatience to start the engine. Is it really needed to buy tensioner keeper or it is enough to use piece of wood as displayed here? http://www.classiczcars.com/topic/19659-nerves-about-timing-chain/ Valve spring compressor is already on the way.

I checked the contact surface between rocker arm and cam lobe - the missing chunk is pretty big so I would rather replace the cam. Used ones are not so expensive. I have also read somewhere it is enough to jack the front of the engine, so hopefully I will be able to do the repairs w/o removing the head or the engine completely.

Here are some follow up pictures. I have removed the oil pan and surprisingly found the entire lash pad untouched! However, there were some small metal pieces - probably from camshaft and/or valve spring retainer (to the right from the release rocker arm). I did find some scores in the cranshaft but I think it is nothing major. 1) small metal pieces 2) undamaged lash pad 3) some kind of silicone sealant

The pan will be definitely cleaned. I have already ordered new sealing. Good to know I can drop it w/o engine removal. I would like to avoid rebuild of the head, cam, valves, rocker arms...but if it will be necessary I might end up with performance cam - at least I have excuse to spend some money Thanks a lot. I will keep you updated.

The cam is really damaged a lot. I was not able to find lash pad, only one small metal piece 5mmx5mm big which really scared me. I will check the wear area and pray for the best. So if I was not able to find any of the missing bits I need to check the "hole of doom" which means get to the front of the engine? Well, great start of restoration project

So I finally had some time to work on the Z. I drained the fuel tank and took of valve cover and this is what I have found. Any ideas what went wrong? Is it even repairable? I did not start the engine, it wasn't running last 12 years.

Thanks a lot. Shipping from US is no problem, so if any of you guys have something nice to sell (and are willing to ship inside US) I am willing to buy

So I finally managed to find a 240z which I always desired. It will take a lot of time to make her beautiful again but I am sure the time spent on restoration will be definitely worth it. Not my first car which will be rebuilt (already completed Miata NA version) so I kind of know what amount of work to expect but I am really afraid of rust. There are a lot of non genuine parts on the car so I plan to get her to stock look as much as possible. First I need to start the car after 12y sitting in a barn. I just can't wait to hear the engine. So if anyone here is selling the parts, PM me I am definitely looking for inspection light, mirrors, seats, front bumper, wheels...

Not my first project car. The other one is Mazda Miata NA so I bought her older sister Thank you for the link to the topic - I have missed it while searching the forum.

Hi guys, I will be soon happy owner of 240z and I would like to get some hints how to begin with bringing her alive.The car was standing for at least 10 last years so I am pretty sure some maintenance will be required before I could fire her up or drive. Any suggestions how to start? I am pretty sure the brakes will be stuck due to rust. I have heard that rear suspension sometimes got stuck due to rust as well. What to do with the engine? Refurbish carbs? Oil/fluid change is a must, no doubt about that. So I will chang all the oils (engine, diff, trans), coolant. Anything else? Sorry for so beginner questions but I do not want to forget anything and take a risk of doing more harm than good.
