Red flags to look our for in an engine when buying a car. Preferably do not rush to start engine, check engine oil level via dipstick, if engine oil colour is very new, be careful! Engine might have been recently rebuilt. Most people who want to sell their cars, do not bother with engine oil changes, and just want to sell of and allow new user do the needful. Engine oil level should preferably be close to the upper mark on the dipstick, if on the lower mark, engine is either burning oil or leaking oil. Oil colour should not be black, this signifies abuse by user or a sludge buildup or oil burn. Engine oil colours to look out for are clear, brown, honey gold, dark brown. Try and avoid black. Next do a visual inspection of engine, look out for fresh silicone gum. When engines are built stock, there is a particular colour/weight of silicone gasket maker used on mating surfaces. www.nairaland.com/attachments/6233514_img20171106142931_jpeg0f50b2a0e57bbbb3b12afec76c8210bd www.nairaland.com/attachments/6233515_img20171106142942_jpeg2c871e3d1e304f20cdc615a3327149a8 When engine is brand new, colour is off-white / light grey. Now what you are looking out for is stock silicone over flow from oil pan, timing chain cover, and possible oil pump areas if visible. In this part of the world we do not have easy access to same type of factory silicone used so if engine has been worked on in the past, you might get to see colours like black, blue, clear, white...... if you find this on areas like timing chain cover, engine oil pan, it signifies previous work on engine. Also look out for no silicone  . Sounds funny, but yes. When working some technicians clean off excess flow of silicone after it cures, giving a better aesthetic look. No silicone on mating surface means engine was worked on previously.Samples engine with previous work www.nairaland.com/attachments/6233555_img20171109125131_jpeg238bab782d37106ef0072e0d23f66344 www.nairaland.com/attachments/6233549_img20171109130341_jpeg036cf61c0d9ced210aaa33fcef65cf90 www.nairaland.com/attachments/6233554_img20171109130332_jpeg01bc0b8683b039465f9d45f7bef6d984 Next inspect the head gasket... All engines leave the factory with steel type head gasket. It is extremely flat and made out of metal.  In most cases when an engine is rebuilt or if it suffers overheating, the gasket is replaced with composite type, usually made from graphite. This gasket is thicker and can be easily identified.  Next inspect for engine oil leaks.... Some oil leaks are expected in high mileage engines, from valve cover gaskets and oil seals. But the cost of fixing a oil leaks vary. While it might cost you about 5k for a valve cover oil leak and take about 30mins to replace on a 4cylinder, a crankshaft oil leak coming from the flywheel area of a V8 will require and engine drop and might cost you over 50,000 in labour costs  so it is essential to avoid the costly leaks  Let me also mention that finding transmission oil leaks from flywheel area in this part of the world is a death sentence to the transmission (Gearbox) as only a few people I know can source the correct parts and install torque converter seals properly. Next look out for different colours...... When an engine leaves the factory (most recent full aluminium engines) they look like this.....www.nairaland.com/attachments/6233574_img20170928184845_jpeg6d3a042b41f9f3ff39cd15999fc3a8af www.nairaland.com/attachments/6233577_img20170928184756_jpeg5bf247ce91cff4ddd1b5fc3fef7cb4a0 www.nairaland.com/attachments/6233581_img20170928184940_jpeg2470277a196c77495270251720108061 Not every engine is made of aluminium, some have steel/cast block engines and aluminium tops. Now when inspecting and you find one part newer than the other, it signifies a part was replaced. It is normal to replace a defective part, e.g starter motor, water pump, p/s pump, alternator... but when the timing chain cover is newer than the cylinder, or the cylinder is newer than the aluminium block, then a serious operation took place in the life of the vehicle. If she's been bleaching, don't take her home Next check coolant level and type...... If water is used, owner is not the careful type, not a death sentence, but better if you observe coloured coolant. If coolant or water is below normal level in the radiator, there is a problem, there might be a leak or engine burning coolant .Next open boot and go through all the stuff in it, it most times reveals the life support vehicle gets Let me explain further... If you find cans of brake oil, powersteering oil, engine oil, small keg of water, sparkplugs, coils, ATF.... it is either owner meticulously keeps them for just in case, or na daily topping ritual Now time to start the engine............ 18 Likes 3 Shares |

somone viewing this thread called and asked an important question about gaskets. Question was if you cannot see the gasket, how would you know if it is metal type or composite graphite type. Example These 2 engines are k24 engines, 1 for a CRV 2002-05 the other for an accord 03-7. One has a replaced Gasket with composite type graphite, while the other is still stock, note the difference in gaps between cylinder and block. Stock metal type gasket www.nairaland.com/attachments/6237728_img20171110101905_jpeg0a2e4955b25de32250307f1af4861e89 Graphite gasket. www.nairaland.com/attachments/6237737_img20171110101854_jpeg3bd27cc31f526383df7e5637e49c6cea I hope this answers you question sir. Now lets start the engine. |

Thanks for this thread, it is so helpful. I intend buying a Chevrolet Aveo 2009 and attached is the picture of the engine shared. Please oga Gazzuzz, I will like you to help use your technical eyes to analyse the engine and also share your view on the brand of the car. Thanks.

One major issue i find with most buys of ignorant buyers is listening for engine noise, either crankshaft or camshaft. The noise cannot be masked on cold start but when its hot, it tends to be quiet especially on idle. Please highlight more on this. |

Starting up the engine.... This is preferably a 2 man job. Sit inside the car and watch the oil pressure warning light while listening attentively to any strange metal grinding sounds. with engine started engine oil pressure warning light should be off in 2sec max, there should also be no rattling sounds that disappear after 5-10secs. There might be a little tapping sounds from the valve area. (due to valve clearance/wrong oil weights) Now the second person should check for bluish white smoke upon startup, that might indicate worn valve stem seals. Also stick your finger in the tail pipe if it comes out greasy and oily it indicates oil burn. If it comes out very dark, engine burns fuel excessively. If it comes out clean/very light brown emmissions are fair. More tips soon.... 7 Likes 3 Shares |

GAZZUZZSCAMMER2:Until you can provide evidences of his alleged scam deals, what you are doing remains spineless, cowardly playground name calling and mudslinging. You cannot come online to start calling people names for no apparent reason, for the sole reason of painting his name black because of perceived hurt. You sound like a pained child. Grow up and sort your personal issues with him like a man and not through some secondary-school style attack online. Mynd44, Dominique, rule 8. 3 Likes |
