Engine Rebuilding in Aberdeenshire
Looking to save some money and improve the raw power and fuel mileage you are looking for? Instead of buying a new engine and having it installed, we will rebuild your existing motor at a more affordable cost. The process of all engine rebuilds is described below.
Sports or Racing Engine Rebuilds
Croft Autotech can do an overhaul or complete rebuild depending on your needs. You know yourself already that it takes a real specialist to rebuild a car engine to use for sport or racing. Scott of Croft Autotech is someone with both the experience and enthusiasm to be able to do all your engine rebuilds.
Everyday Car engines
Obviously with the knowledge of how to rebuild a hi powered sports racing car we are able to do the same for your everyday street car.
- Do you need a bit more bottom end power for hills?
- An increase in acceleration for overtaking other traffic?
- Better fuel economy or to cure an overheated cylinder head?
Croft Autotech can fix it for you.
What’s Involved in Fully Rebuilding An Engine?
The first thing we do would be to dismantle the engine to give it a thorough check. We need to make sure it can be safely re-bored as part of a complete engine rebuild. Before we can do that we need to clean down the whole engine using an environmentally safe but effective car engine cleaner. By the time we have finished that process it looks as good as new.
The whole motor is then checked for visible cracks to make sure it is still good enough in order to rebuild the engine. If not we may be recommending starting with a different engine.
At this stage of all engine rebuilds we look at skimming the cylinder head along with surface grinding and pressure testing.
This would also include where necessary a number of other options including
- Valve and valve seating re-cutting (or replacing with new hardened seats depending on type and condition of the valve seats).
- Valve Tappet shimming
- Line boring and honing the camshaft housing
- PPC Fitting
All this would be as part of the complete dismantle and assembly of the cylinder head. A very necessary component of all thorough engine rebuilds.
If necessary we will be looking at boring and honing each of the cylinders. Refacing and re-sleeving along with line boring and honing to ensure all necessary work is completed to give a top class result.
Crankshaft and camshaft reworked
We now turn to cleaning the crank and camshaft. This will enable us to check the camshaft for bad lobes or scrapes before machining and re-facing the camshaft followers. The crankshafts are checked for straightness prior to regrinding and polishing. This is an essential part of any engine rebuilds carried out.
All connecting rods will be checked prior to machining, resizing or straightening or re-bushing.
We all know the importance of a first class oil pump. All engine rebuilds should include the oil pumps are stripped down for a thorough check prior to being reassembled.
Final engine assembly following a full rebuild.
After a final cleaning new oil sump plugs are fitted prior to the cam bearings and the reworked camshaft being installed in the engine block. Next, comes the crankshaft and new main bearings along with the connecting rods. New piston rings and rod bearings are added before installing push rods, rocker arms and full adjustment of valves, timing belt, chains and tensioners. Many engine rebuilds skip the timing adjustments but this is considered by us as an important part of the final tune-up.
Your new rebuilt engine is ready to rock and roll. In many cases, your engine will now be even better than new. Think Engine Rebuilds is like a new engine but cheaper.
