 Shown is the bottom side of the 4.154 head. If you look at the perkins manual. The only difference is one is a short stroke engine and the other is a long stroke engine. Comparing the differences in heads..- The 4.154 head has injectors that are straight up, the 4.135 injectors are angled. Part number for the Mazda 4.135 Cylinder head is: 145610100D Part Number for the Perkins 4.154 Cylinder Head is: 136310100C ( or D ) The History of this engine is as follows. In the mid fifties the original engine design was produced and used in a few Farmall tractors, MF, Marine GenSets Westerbeke also made a variant for marine applications called the Westerbeke W52 www.westerbeke.com/advanced%20specs/w52.pdfPerkins 200 series Specification / manual www.manualslib.com/manual/1001777/Perkins-4-135.html?page=14#manual  Here you can see the displacement in the cylinders changes, as well as the oil capacity. The main differences between a pre 200 Series engine family is the injection pump and pistons/rod. Allthough called a 4.154 the engine isn't fully interchangeable. Earlier version of the engine included a CAV style fuel pump The later 80's version of this engine in Bobcat, Mazda, Gensets and more features a Japanese Diesel KIKI pump. This is why they call the perkins 4.135 4.154 4.182 the "Japanese engine" because the older ones were made in England or USA. One big difference is the earlier North American version came with 5 ring pistons and different connecting rods. ( then they switched to 3 ring with the 200 Series Japanese engine the piston mass was shorter because it didn't use a bottom ring and the rod was longer ) Likely to save cost.  Here below in this image you can see the 4.135 engine head injectors are angled differently. The 4.154 injectors are straight, the 4.135 injectors are angled. This is the only difference between the 2 as far as I can tell. Which would mean fuel rails would need to be matched but theoretically you could build a hybrid off the old head if the .135 head is in good shape. ( this has not been confirmed by anyone ) The Crank is different, and the pistons are slightly different between the 2.2 and 2.5.  If anyone would like to contribute to the revival and networking of restoring these engines please post pictures of your 4.135 Cylinder head etc, or if you know differences and can explain them please do so.  4.135  ------------------------------- 4.154   If you look at the available manual online for the 200 series you can compare everything. Very similar, even the mazda/ford 4.135 head gasket is reported to work on 4.154 engines. The question is does the head bolt on to the 2.5 block ? Attachments:

Great info! Awesome first post! Welcome aboard! Thanks! I find it extremely unfortunate that these engines have almost lost all hope. Having my hands on the parts of this engine after 5000 hours, and only if the previous owner wasn't a goof and took care of the engine it would of ran another 5000 hours. It's a beautiful design and deserves to be brought back to life. |

 Well there it is.. The illusive 4.135 Head bottom side. Looks like the Mazda didn't include the fuel channels in the combustion chamber. Instead it's a flat design. Not sure if it would work or not. |

On the 4 154 the recess is in the head and the pistons are flat top and on the 4-135 the piston has the recess and the head is flat. Using the 4-154 head on the 4-135 would lower the compression. It might work well for building a turbocharged engine. A while back someone on the forum had gotten a new head as I remember from china. Kia also used them for some market. I have seen a genset at an auction with the kia valve cover. The main difference was that the bolt holes and studs were metric threads instead of american like the ones produced by Mazda.

yes, the lower compression would be better with turbocharging. also getting the rods and pistons that have the piston cooling would be important. i believe the bolt pattern is the same for the heads. the injectors however are a different style.. the 4-154 heads might be easier to find....
my ranger is getting tired. when i get a newer small pickup i'm considering using the rangers engine for a generator set...

The 4.135 (as well as the 4.154 and 4.182) all have Tenifer-treated (case hardened) cylinder heads.

May be a dumb question but what exactly does "case hardening" do for the heads?

Thanks! I sorta knew it made the head more hard but didn't know about the anti corrosion properties, pretty cool!

Keep your legacy alive. I have two complete engines and transmissions for sale.

You have some pictures of those trannys? Been considering investing in a spare.

Thanks for the info above. In the process of rebuilding my Westerbeke W58, which as it turns out is Mazda XA/Perkins 4-154-200 series (Japanese version). Perkins and Mazada parts are half the price of the Westerbeke and much easier to find. Been a fantastic diesel. 37 years old and have never had to do anything to it except normal maintenance until now. Never burned oil and less then half a turn to start. Left it for 6 month and now head gasket is gone. Water in the cylinders.
