peppi_sun510 Posted June 17 Report Share Posted June 17 Hello I am Steffen from Germany and I restore a Datsun 510, 4-door For a complete original engine rebuild I need 4 Intake valves and 4 exhaust valves with 8 new pressure pieces valve stem. My engine number is: L14-175602 thank you for your help sincerely yours Steffen Quote Link to comment
banzai510(hainz) Posted June 17 Report Share Posted June 17 I beleive the L14 is the same as a L16 in valves. Maybe the L16SSS head has the bigger valves but in America the stock 510 had L16 with a 210 marked head and should have the smaller valves Viellicht findet ein Datsun 180B mit ein L18 cylinder kopf es passt 1 Quote Link to comment
datzenmike Posted June 17 Report Share Posted June 17 Look along the bottom of the head between the #1 and #2 spark plugs for the head ID. As stated it's likely a 210 Measure your valves. The 210 intake valves are 38mm and part number 13201-A3000 The exhaust valves on the 210 are 33mm and part 13202-23001 If you have a 210 head but the valves are smaller let me know as there are L13 valves listed and maybe they are used on the L14. I don't have the diameters for them but if smaller than the ones above then probably same as for the L13. Valve seals are 13207-21002 same as for all L and Z series engines. Also used on the early (mid '80s 300zx and FWD Maxima with VG30E engines. The 210 head has very small ports compared to other L series heads and it's rumored than the 210 was designed originally for the L13 or L14 but used on the L16 possibly with larger valves. 1 Quote Link to comment
peppi_sun510 Posted June 19 Author Report Share Posted June 19 Hello! Thanks for the help! Yes, the number 210 is between the first and second spark plugs. The valves have the following dimensions: Inlet valve: - Length 116mm - Head diameter 38mm - Shaft diameter 8mm Exhaust valve: - Length 116mm - Head diameter 33mm - Shaft diameter 8mm Thanks for the part numbers! Unfortunately, I can't find any valves online based on the dimensions. Do you have the option of buying/getting some and sending them to me? Best regards, Steffen Quote Link to comment
datzenmike Posted June 19 Report Share Posted June 19 Haven't seen a 210 head since the mid '80s, sorry What's wrong with the valves?? They can be reused by refacing them and replacing the seats. Often you can just lap them and replace the oil seals.. Quote Link to comment

banzai510(hainz) Posted June 19 Report Share Posted June 19 (edited) It cant be that hard to find parts there but when I was there there is not alot of old cars around!!!!! Even the junk yards the cars still looked NEW, People dont even wash their car at home. Car wash recycle the water ect.... Edited June 19 by banzai510(hainz) Quote Link to comment

peppi_sun510 Posted June 20 Author Report Share Posted June 20 You're right, there aren't many car lovers left in Germany. Young people like me, who are 30, in particular, make the effort to buy and restore such old cars. The days when cars were washed on Saturdays in the driveway of every street are unfortunately over. Nowadays, you're more likely to get a police report from your neighbor than to talk about your car...poor Germany Thanks for the part numbers! I also looked at Rockauto but didn't find anything under the Datsun vehicles... I'll take a look right away! Thanks to all of you! Greetings from Cologne Quote Link to comment
peppi_sun510 Posted June 20 Author Report Share Posted June 20 Hello everyone, I looked for the part numbers and found them, but most of them are no longer available... The Melling V5014 have a head diameter of 42mm, but I need a diameter of 38mm. I also need the valve stem pressure pieces, do you have a part number for me? Quote Link to comment

I just looked up a 1970 and it shows 33mm intake and 38 mm exhaust ... Also the pressure pieces, are you referring to the valve guides? If so those are there as well, plus seals. 1 Quote Link to comment

Looks like rockauto has them too, seems like they only sell the hardened ones now so that's good..... Peppi you may have to cross reference some of the number to find them some where... exhaust is avaliable but intake is not at the moment.... 1 Quote Link to comment
banzai510(hainz) Posted June 20 Report Share Posted June 20 (edited) this was years ago but there was a guy in England that was like a datsun parts guys. this L14 motor was common in Greece so maybe try to find a Datsun guy there https://www.ebay.com/itm/355521563811?fits=Model%3A510|Make%3ADatsun&itmmeta=01J0V0FTB9V228JBF80Y774PCX&hash=item52c6bc8ca3:g:AQAAAOSwyOJk-LgA&itmprp=enc%3AAQAJAAAAwNAU0tP4NvW9iborzF5RW4MUqZ77lvx0xzrlnUyBNjB%2FfflgB%2B5SjAcgCJdAMujhgYoVIbmcm256Lhpyi3MS3ACMkIP9yoaL3U4VzVAFoy1NXh5epVwCOTHbdBkds%2Bauyxnwkdb6wJG0TDU%2BqYQYm1nPbS58imcNCsEEASkxgfWr%2FUNnhRabpb1qGqP%2FvBnKOo%2FBnY7DiK%2F1RcVXfezaKP0EVrEgg0F%2BQ1Dp1%2Fh7sojYj3yErjn%2FOYNlD57skSVV3Q%3D%3D|tkp%3ABk9SR9qlv-CGZA Edited June 20 by banzai510(hainz) 1 Quote Link to comment
peppi_sun510 Posted June 21 Author Report Share Posted June 21 Thanks again to everyone! That's really nice of you! My 510 is from 1972. The dimensions of the valves that I own are the same. I have the valve stem seals, as well as the valve guides. By "seats" you mean the place where the valve heads fit in so that it has a flat finish to the cylinder, right? How and with what can I get these seats? Do I need a new cylinder head? The "hardened" valves that you mean, are they the ones with the 42mm head diameter or are they different ones? The eBay link still works and he still sells the valves, but he doesn't deliver to Germany... 😞 I've already written to the Greek seller and am registered in a Greek Facebook group, but no one has replied there yet Quote Link to comment

If you know of a good machine shop, they can install larger valves for not much money. It is a basic machining process which requires cutting out the old valve seat, machining the aluminum casting to accept the larger seat, and installing the seat, followed by grinding or lapping the seats to the valve. A good 3 angle valve job is standard practice these days too. If you went this route, make sure the shop opens up the port behind the new valve seat. This is what we call the valve pocket. No idea what you would call it in German. Quote Link to comment
iceman510 Posted June 25 Report Share Posted June 25 I'm sure I can come up with some of these smaller valves if you need to keep the original sizes. 1 Quote Link to comment
